In late 2012, Scott confirmed his interest in making a full-length Ninjago movie with a more serious tone than the TV show. In March 2013, he confirmed the film is in production, and casting for voice actors began that April. Filming took place from May to November. The film began airing on YouTube on July 7, 2014 and concluded on December 11. It gained a generally positive reception.
A shortened version of the film was released on March 28, 2015, and a sequel, Ninjago: Rise of the Great Devourer, aired from July 2015 to March 2016. A third film, Ninjago: Age of the Golden Master, began airing in July 2018.
Sensei Wu (AckarProductions5) narrates the history of Ninjago City, a sacred place created by his father, the First Spinjitzu Master, and also plagued by darkness and corruption over the years. In 2010, Cole Hence (Jack Morris) is training with several teenagers to become Ninja and work together to protect the city. Cole's father, Lou Hence (BioPower OneThousand) is the head of a project to build a dam in Jamanakai Village for the poor side of the city. Near the end of the dam's construction, an attack by the Hypnobrai and Fangpyre Tribes on the dam results in many deaths, with General Skales (Collector1100) killing Lou in the chaos before the Serpentine are detained once more. Sensei influences Cole to avenge his father by becoming dedicated to his role as a Ninja.
Four years on, Cole has completed his training for the time being but has become depressed, unable to see if he has a true purpose in life. Sensei converses with Cole over the role he is destined to take on until they meet with the other Ninja, Jay (OonieandCacola), Kai (Ryan Bowman) and Zane (Westificationful). The following morning, Dareth (Collector1100) is scouting around Jamanakai on a boat until a pirate ship, Destiny's Bounty, arrives. The Ninja suit up while Dareth and a corrupt politician, Cillian Fincher, are taken hostage by Captain Soto (JTH Studios). The Ninja battle Soto's pirates and save Dareth and Fincher. Sensei tells the group that a fault appeared outside of the village that morning, which he believes went by the tomb containing the Hypnobrai and Fangpyre Tribes. During the discussion, Lloyd Garmadon (JTH Studios), the son of Lord Garmadon, frees the two tribes before going to the Slither Pit, where they plan a terrorist attack on Jamanakai Village by blowing up the village's main electrical barrel. Lloyd and his army, as well as Destiny's Bounty, arrive in the village, where they fight against the Ninja and the police. As the Serpentine retreat, the Bounty is damaged and crashes.
After the battle in Jamanakai, Captain Rezzle (ToaGresh300), the head of the city's military, tells the Ninja that he will ally with them, and the police do the same. Zane repairs the Bounty while the Serpentine prepare a second assault, prompting the Ninja and police to head off and stop them. Cole sees a Rattlecopter carrying Skales heading for the Slither Pit, to which he has Jay ride the Tread Assault into battle. The Ninja and police head towards the Slither Pit, and they encounter Lloyd and Fangtom (FireStar97Studios) riding a truck carrying explosives. In Jamanakai, Sensei and Dareth fly the Bounty and defend the electrical barrel from Fang-Suei (Westificationful), who pilots a Rattlecopter carrying explosives. Cole confronts Skales in the Slither Pit, and berates him over the murder of his father.
The final battle ensues, with the Ninja pursuing Lloyd's truck while the Bounty battles the Rattlecopter and Cole fights Skales. Fang-Suei, Snappa (Westificationful) and Johnson (Draco Jet) are killed in the chaos. Jay shoots the crate of explosives off the back of the truck, forcing it to head back towards the Slither Pit. Zane makes several unsuccessful attempts to get onto the truck and obtain Lloyd, as per Sensei's orders, while Cole is incapacitated by Skales before making the decision to stab him in the stomach and kill him. Zane apprehends Lloyd while Jay and Kai chase the truck alongside the Slither Pit before forcing it off the side of the cliff, destroying it. The Ninja and police regroup in the Slither Pit, with Zane proposing that they make a move to unite the people of Ninjago City and promise a secure future.
Mason Davis announces his retirement as the city's police commissioner and Delmar takes his place. Sensei tells Cole that he respects the decision he made to kill Skales, although he cannot teach him how to live with a mistake. After Cole regroups with the Ninja, Sensei goes back to the base and has a persuades Lloyd to become a Ninja in order to save his father, which Lloyd considers. The film ends with Cole, Kai, Jay and Zane standing together and wondering what will happen in the future.
In an after-credits scene set in the Underworld, Bonezai tells a shadowy figure that "he would like to see you". After Bonezai leaves, the figure is revealed to be Lord Garmadon.

LordStarscream100 first developed the concept of Ninjago in December 2012. At first, he stated that the film will represent a new and more serious view on the story. However, it will still have many similarities to the TV show and story, although the film will not be a dark movie. Voice casting officially began on April 12. In July, Luke Perakovic resigned from the voice of Lloyd Garmadon due to technology issues, and the role was then given to JTHStudio, who will also voice Mezmo. On July 29, it was confirmed that filming would begin in March 2014 and conclude in early-June 2014. On the same day, the film's first screenplay draft had been completed.
A teaser trailer for the film was released on August 29. Writing for the film's official screenplay is currently underway as of September 15. Soon afterwards, it was confirmed that LordStarscream100 had sent out a message to all of the film's voice actors asking them if they are still voicing their respective characters. Various people were resigned from their roles after not replying, although Cielphatomgive has resigned from the voice of Lord Garmadon for various reasons. On November 10, it was confirmed that the film's script was complete, with revisions set to take place soon. On January 2, it was confirmed that CarpenterStudios had resigned from the voice of Zane, choosing to focus more on Kai instead of dealing with two main protagonists. GreshLord, who was set to voice Mason Davis and Fangtom, was offered the role of Zane and chose to voice both Zane and Mason Davis on January 4. On January 6, FireStar97Studios signed on to voice Fangtom and Lord Garmadon.
Throughout January and February, the film was undergoing screenplay revisions, as well as modifications to the cast. The first official trailer for the film was released on February 20. On February 26, it was confirmed that Whatsupwithcomix (now Cameron Morris), who had been cast out of the role of Ben Delmar due to his inactivity on Youtube, was recast as Anthony Reese. Previously, ToaFirestorm was recast as Ben Delmar. On March 7, LordStarscream100 confirmed that the revisions for the script were officially complete. On March 18, LordStarscream100 confirmed that he had finished organizing the lines for over twenty different characters. Lines were handed out to approximately sixteen different voice actors.
On April 3, LordStarscream100 confirmed that filming has been moved to an unspecified date due to the damage to the set. He has also confirmed that the film's release date has not been altered as a result of this. On April 10, Cameron Morris sent in the first set of lines for the film, completing his role as Anthony Reese. On April 19, LordStarscream100 confirmed that KookKidsPictures was forced to drop out of the role of Captain James Soto. LordStarscream100 originally took his place, as he didn't have time for a recasting and didn't want to overwhelm the current voice actors with the offer, but due to various recastings JTHStudio wound up taking his place in the role. On May 17, Lewafire12 was cast out of the role of Dareth, as he had not been responding to LordStarscream100 about the status of the role. Collector1100 was officially recast as Dareth.
On May 27, LordStarscream100 confirmed that the entire film would not be released on June 20. On June 11, Shadow Raven Productions resigned from the role of Cole Hence, citing the fact that he would not have the time to do it. Having lost the actor for its main protagonist and without several of its major voice actors, LordStarscream100 was forced to postpone the film by two weeks. On June 25, LordStarscream100 confirmed that Jack Morris has officially been recast as Cole Hence. He submitted his lines the day of the announcement. The release date was later pushed back from July 4 to July 7 after the file that contained the first portion of the movie was corrupted. On September 7, the second part of the film was released.
On October 10, it was confirmed that Ryan B would be taking over the role of Kai Fellows. Fellows was voiced by CarpenterStudios in parts 1 and 2, and was set to continue for the remainder of the film, but because of problems with getting voice lines done for a long period of time, had to drop out of the film. Ryan B's lines will be used from here on forward, and will also voice over the segments from part 1 and 2 during the full movie's release. Part 3 was released on November 10, with a larger running time of 45 minutes. It was originally set for release on November 9, but was bumped a day further due to a major audio problem with it. On November 12, LordStarscream100 decided that before editing on the film's two final parts would commence, he would go back and revise the lines from the first two parts whose voice actors had been switched. Part 4 was released on November 30, and Part 5 was released on December 11, concluding the film's production.
Filming officially began on-location on May 5 and was completed on November 15. For several days, Scott had to rebuild the set because a major flashback scene was being filmed using a large part of it. The scene, which depicts Jamanakai Village four years before the actual events of the film, was shot in May before being swiftly modified to the modern set. The new and rebuilt version, which acts as the present day, is used for the rest of the film.
As judged by the five parts and both halves of the full movie of Ninjago, the film has gained a generally positive reception, gaining a 78% rating based on 1,781 likes and 492 dislikes. When combining the reception of the film itself and its trailers, it also has a rating of 78% based on 2,610 likes and 735 dislikes. Much of the negative reception that came here was with the film's second trailer, which was released in February 2014 and gained a mixed reception because many people believed the film was "fake". The rest came with the full movie, which gained more of a negative reaction because it is not necessarily an "official" movie, as some would call it - however, it was never advertised to be such.
Because many people were confused with the two full movie videos, as they believed the film was a scam for the upcoming 2017 Ninjago film, a portion of the dislikes are due to the confusion. Daniel Poulter, best known for directing LEGO Ninjago: The Animated Movie and its sequel, Day of the Nindroids, praised the film for its unique directing style and animation. Daniel wound up joining the cast of the film's sequel because he enjoyed it so much.
Currently, according to Scott's analytics, the film set the record for having the biggest Part 1 debut, gaining 550 views three months after its release. In comparison, Jurassic Shark had around 350 views three months after its first part debuted, while its sequel had around 300. The first half of the full movie, which included all the scenes leading up to the film's final battle, has gained nearly 1,000 views about a week after its release. Ninjago also went four months with having a solid 100% rating, maintaining 46 likes and 0 dislikes before the release of Part 3.
Looking back on the film, Scott believed it could've been better in several areas, namely with its editing and sound design. He believed the awkward cutting of shots, as well as the lack of sound effects, were his two biggest flaws with the project.
- This was Scott's first film to feature a post-credits scene.
- The minifigures for Vladimir Dubrovky and the soldiers, except for their head molds, were given to Scott by Ryan Bowman, who voices Vladimir in the film.
- The casual outfits worn by Kai and Cole are the outfits worn by the two criminals featured in 4853 Spider-Man's Street Chase, a LEGO set released alongside Spider-Man 2 in 2004.
- Captain Soto's torso and hair pieces are the same ones used for Aragorn in The Lord of the Rings sets. Scott sought to create a more "realistic" look for Soto instead of giving him such features as a peg leg, eyepatch, and hat, choosing to base the designs of him and the other pirates off of modern day ones.
- After Cole stabs Skales in the stomach with his sword, he says, "Your fate was sealed when you first stepped into this village", but the scene takes place in the Slither Pit. This is actually a minor flaw in the script, as the entire scene was originally set to take place in Jamanakai Village. Scott decided to change the scene at the last minute.
- As a matter of fact, there weren't any changes to the script when the location was switched. The original script would fit perfectly with the environment of the Slither Pit, as Scott noticed. He felt that setting the confrontation between the two characters there would be much better for numerous reasons, including the fact that it would tie in neatly with the ending chase scene.
- AckarProductions5 is credited as Ackarproductions5, with the "p" not being capitalized. Scott made this error because he was so used to seeing YouTube usernames that "needed" capilization in some places but they didn't have it. He was credited properly in the sequel.
- Simon Bowler, a government agent who previously appeared in the BIONICLE Universe series, returns in this film as the creator of the Ninjas' suits, technology, and other devices. In the TV Show, Cyrus Borg, the head of a technology company, wound up doing the same for the Ninja in Curse World - Part II, as he created several new vehicles for them.
- As revealed in Ninjago: Age of the Golden Master, Bowler is indeed the son of Cyrus Borg.
- When uploading the film's separate parts to YouTube, Scott would combine several smaller videos into a single video using the YouTube Editor. Unfortunately, an update to the editor prevented videos with copyrighted content from being used in the editor. This caused the third part of the film to be delayed at the last second, as some of the music it used was copyrighted. As a result, Scott replaced much of the music.
- Scott was very cautious when moving Destiny's Bounty around in the action scenes, particularly when it flies over/around the creek, sometimes at high speeds. If the fishing wire broke, the Bounty would likely be heavily damaged and the sails would also be destroyed because of their paper-like material.
- During the Bounty's final scene, where Sensei and Dareth are using it against Fang-Suei's Rattlecopter, one of the fishing wire strands snapped. Fortunately, the Bounty was barely hovering above the creek, and the back of it landed on a mud bank, unharmed.
- The film surpasses Jurassic Shark III: The Revolution as LordStarscream100's most positively-received full-length movie. Jurassic Shark III has a current rating of 79% (exact - 78.95%, while Ninjago has a current rating of 80% (exact - 79.97%).
- However, the reception for Jurassic Shark III is currently only based off of the film's first part, as the rest of the film has yet to be released. Jurassic Shark II: The Retribution is also close, with a rating of 77% (exact - 77.77%).
- In the BIONICLE Universe films, Captain Rezzle appeared as a toy military figure, not a LEGO minifigure. In this film, while it is still the same character, he appears as a LEGO minifigure.
- Simon Bowler also appeared throughout the BIONICLE Universe trilogy in minifigure form, and he appears the exact same way in this film as he did back then.
- As of July 2018, the film is Scott's most successful "full movie" in views. The first half of the film's full movie has nearly 230,000 views.
- The Ice Dragon that Zane flies is not an Elemental Dragon, as confirmed by Scott. Elemental Dragons were introduced in the fourth season of the TV show. Scott hasn't confirmed whether such dragons exist in the series' canon.
- Kai and Zane appear in their original ninja outfits during the flashback. For the rest of the film, they wear their ZX outfits along with Cole and Jay.
- Dareth is described as being a friend of Jay's and also his partner in the film.
- The base for the Ninja was always envisioned to be in the tree that it wound up being in, and when Scott first put it in the tree, it fit perfectly amongst the vines.
- Lloyd Garmadon never appears as the Green Ninja in the film, although his ending conversation with Sensei Wu hints at this future role. Scott chose to have a different take on the character, in which he's truly set on following in his evil father's footsteps.
- In the canon storyline, Cole's father and Skales never die, and have made numerous appearances throughout the TV series.
- In the original version of the script, Cole, Kai and Zane go on a journey to find the Ice Dragon, which was in a deep slumber in a more rural part of the city. The scene was scrapped when the entire plot of the film was changed, in which the Ninja weren't actually training in the midst of the story.
- The Nunchucks of Lightning were replaced with the Sais of Lightning because they would be easier to film in fight scenes. Ironically, Jay never used them in the film. For the sequel, Scott retconned the sais and changed them into the Nunchucks of Lightning.
- Another major aspect that was retconned was the name Spinjitzu City, which was changed to Ninjago City. Scott changed the name originally because he found it odd to have the word "Ninja" in the city's name, but later decided this was a poor decision.
- In the original script, Dareth was a much different character. He would be captured by the pirates and saved by the Ninja, just like in the film, but in the original script they wouldn't know him personally. Dareth would discover and enter the Ninjas' base, where he'd encounter Sensei and Jay. The Bounty would attack the base, with Jay losing his mask in the chaos (the Ninja would hide their identities as well). Sensei would then allow Dareth to help Jay fight Lloyd's forces. Scott scrapped the scene because it felt like an awkward introduction for the character.
- The geography of Jamanakai Village in the film is far different from in the original storyline. It also plays a larger role as well.
- Shadow Raven Productions was set to voice Cole. He even voiced the character for the film's two trailers. However, in June, he was forced to drop out of the role due to a lack of time to complete it.
- Cameron Morris was the first person to send lines in for the film. He later recommended his colleague, Jack Morris, to take the part of Cole Hence after Shadow Raven Productions dropped out.
- Douglas Garthwiate was originally cast as Fangdam. When Scott found out that the character is mute in the canon storyline, he cast Doug as Snappa instead.
- It required one strand of fishing wire to move vehicles such as the Tread Assault, Fangpyre Truck, and the police boat and cars. It required two of them to move aerial vehicles such as the Rattlecopters and the Ice Dragon. Due to its immense size, it required three separate strands to move Destiny's Bounty when in aerial mode.
- For the scenes where the Tread Assault and Fangpyre Truck "flew" over the Serpentine Tomb, as well as the scene where the truck shoots off the side of the Slither Pit, flies through the air and crashes to the ground below, utilized two strands of fishing wire.
- FireStar97Studios was originally set to voice Lord Garmadon in the film. In fact, the role was included in the script and he even recorded the lines for the character. However, Garmadon's major scene in the film was cut out because LordStarscream100 felt it did nothing but foreshadow future plot elements that didn't pertain to the film. In the after-credits scene, Garmadon's response to Bonezai was supposed to be, "and so, he shall." However, LordStarscream100 decided to keep him silent in the scene. Ultimately, FireStar97Studios went uncredited for his work on Garmadon.
- He was set to voice the character in the sequel, but because LordStarscream100 felt that his portrayal of the character was out of his expectations, 1tjmac12 was recast in the role.
- The film was originally set to run anywhere from 120 to 140 minutes in length, although due to its opening scenes and exposition, which totaled around 40 minutes of the final product, the film's running time exceeded 180 minutes. Half of the exposition focused on the flashback scene and meeting the characters, while the second half focused on the introduction of the ninja. The film's director's cut only runs at around 121 minutes.
- Two of the film's soldiers, Roberts and the Russian Soldier, are both voiced by Ryan B. While LordStarscream100 sent him lines, Ryan heavily improvised many of them for the characters.
- Lloyd Garmadon's hair in the film is not black. It is really blonde like in the original story, but he dyed it black because he felt it would make him look more intimidating.
- Destiny's Bounty is heavily modified from the original set. It features a pulpit, a larger deck, and a blaster on its cabin. It is also able to float, although there are issues with it filling up with water.
- The Rattlecopter is more of a Rattlejet if anything. Scott modified the original set into a jet, although he decided to stick with the title of "Rattlecopter" because it sounded catchy.
- Unlike the original series, Lloyd Garmadon's "initial role" is expanded in this film, as he becomes a bigger and more serious villain than in the TV show. He is also not featured as the Green Ninja in the film, although at the end his conversation with Sensei Wu hints at the role he will adopt in the future.
- The Golden Weapons briefly appear in the film. While three of them have no part in the plot, Cole obtains the Scythe of Quakes in his final fight with Skales. Scott says that originally, the Ninja were set to use them throughout the film, but he forgot to make this concept come to fruition.
- Excluding the scene where the ninja receive their vehicles/gear and the initial conversation between Davis and Reese, the film was entirely shot on-location in the woods.
- Approximately 7,800 different videos were shot for the film in all.
- Jay is the only Ninja whose voice actor did not resign from the role. OonieandCacola stuck with the role all throughout the production. Shadow Raven Productions, CarpenterStudios and GreshLord all resigned from the voices of Cole, Kai and Zane, respectively, before their longtime voice actors were cast.
- AckarProduction5, OonieandCacola, Westificationful and Cameron Morris are the only voice actors who made it all the way through the production that began in April 2013 (Cameron Morris did wind up being removed from the cast for a time, although after his return he was recast from Ben Delmar to Anthony Reese). All four of them return as their respective characters for the sequel.
- Ninjago is the first example of any of Scott's films where his actors have also done voice acting; where Russell Parkinson played Cillian Fincher and Ryan Bowman played Kai Fellows.
- Unlike the rest of Scott's LEGO-based films (namely the BIONICLE: Universe film series), all of which used stop-motion animation, Ninjago was filmed and produced entirely live action, save for post-production special effects and sounds.
- In the original script, Lloyd was to unleash the Hypnobrai first, and go with them to unleash the Fangpyre in a separate tomb. To improve pacing, both tribes were put in a single tomb.
- Originally, Mason Davis was set to die by Ben Delmar's side at the end of the film, following the chase scene at the Slither Pit. The scene was never written into the script, and Mason's death was instead postponed to Rise of the Great Devourer, at which point Scott felt his fate better fit the story.
- The sounds made by the Ice Dragon were also featured several times in the TV show, such as in episode 70, when Lloyd uses his Elemental Dragon to fight the Vermillion.
- Captain Rezzle, Simon Bowler, and the pilot at the beginning of the film (whose name is J.T. O'Neill) appeared in the BIONICLE Universe series. Rezzle appeared in the first and third films, O'Neill appeared in the second and third films, and Bowler appeared in all three films.
- At the beginning of the film, Sensei mentions that Kai and Zane are in Ignacia dealing with the Fangpyre Tribe. This is a homage to the first episode of the TV show, in which Wu visits Kai and Nya's Blacksmith Shop in Ignacia.
- Lloyd Garmadon's line "Fair? Fair isn't a word where I come from", is from the original storyline, where Lloyd himself quotes a comic book character he idolizes.
- In the fifth season of the TV show, a new technique called "Airjitzu" (which is essentially aerial Spinjitzu) is introduced. Coincidentally, Scott's portrayal of Spinjitzu in the film is very similar to the way Airjitzu works, in which instead of the user doing Spinjitzu on the ground, they do the same thing but in the air, and hover upwards.
- Just like in the TV show, Lloyd Garmadon makes his first "attack" on Jamanakai Village. In the TV show, he went there with the Serpentine to steal candy.
- The First Spinitzu Master's look in the opening of the film is based off of his look in the flashbacks from the TV show. He has Zane's head in the film because Scott saw a similarity between the two.
