The film will be based off of three seasons of the original TV show - Rebooted, Tournament of Elements, and Possession, and it will be loosely based off of the sixth season, Skybound. The film is set to revolve around an all-powerful being known as the Golden Master, a character that originated from Rebooted. Scriptwriting for the film is complete, and filming is over halfway complete as of November 2017. The film is set to start airing in 2018; an exact release date has yet to be determined.
Two years after the second film, Pythor (1P Entertainment) has formed an alliance of villains, and seeks to build a terrible weapon for an all-powerful being - the Golden Master. The Ninja and their trusted allies are thrust into a dangerous conflict, and must fight across Ninjago to save the city from an age of destruction.

The first Elemental Master of Earth, who appeared in the teaser trailer for Rise of the Great Devourer, will appear at some point, as confirmed by the teaser trailer. Several other original Elemental Masters are set to appear as well.
These are the vehicles that have been confirmed to appear in the film at some point.
- Destiny's Bounty - A colossal aerial ship designed to fly and float in water. Once manned by Captain Soto and his crew before the Ninja took the vessel, Destiny's Bounty was shredded apart by the Great Devourer at the end of the second film.

- Destructoid - A tank-like vehicle with a sword and sawblade, utilized by the Nindroids.
- Fangpyre Truck - A large green truck built by the Fangpyre Tribe to assault Jamanakai Village in the first film.
A crashed Rattlecopter was briefly seen in the film's teaser trailer.
The film was planned as far back as 2013, when Scott began pre-production for the series' first film. He intended to make the series a trilogy, though at the time he had few ideas for the third film. At this point, Ninjago only had two seasons and the lore wasn't as expansive as it would be three years later. The film was officially announced on July 3, 2016, as the third and final installment in the series. JTH Studios stated he is interested in reprising his role as Lloyd if he's expected to, and was the first person confirmed for the cast. On July 4, Jack Morris and Westificationful, who voiced Cole and Zane in the first two films, confirmed they're returning for the film. On July 5, Biopower 1000 (now known as Bio21) was confirmed to be reprising his roles as Acidicus and Samuel Mercer from the second film, and GarnettFox was confirmed to be returning as Skalidor. The same day, Daniel Poulter was confirmed to be reprising his roles as Lucas and Snike. On July 6, AckarProductions5 was confirmed to be reprising his role as Sensei Wu, and he is also interested in auditioning for new characters as well. On August 6, 1P Entertainment (formerly 1tjmac12) was confirmed to be reprising his roles as Garmadon and Pythor in the film. On August 13, OonieandCacola was confirmed to be reprising his role as Jay, and on August 22, FireStar97Studios was confirmed to be reprising his roles as Ben Delmar and Fangtom.
Returning/New Major RolesEdit
On September 1, Scott announced that he is entering a contest for Brent Miller, who voices Zane in the Ninjago TV show, to have a role in the film. Before the contest ended, Scott garnered nearly 70 supporters, including his personal friends, members of the film's cast, viewers of the series and other random supporters. On September 15, Brent Miller announced the winners of the contest, with Scott winning the vote for the smaller channel, and DTinaglia Studios winning the vote for the larger channel. Throughout October and November, Scott worked to rewrite the opening scenes of the film, feeling they were poorly written and boring, and that they needed to set up the film's new main characters better.
Filming officially began on November 11. On November 28, Joe Newman was confirmed to have joined the film's cast as Clouse, Cryptor, Karlof and Flintlocke. On December 1, NinjaBoys was confirmed to be returning as Lizaru, Spitta and Bytar from the second film. On December 28, YamatoGuru was cast as the voice actor for Morro. On December 29, Ryan Bowman was confirmed to be returning as Kai and Vladimir for the film. Ryan was confirmed for the cast back in July, though his return wasn't officially announced until this date. On December 30, Rob O'Dwyer was cast as the voice actor for Master Chen. The following day, he was confirmed to be voicing The Overlord, replacing 1P Entertainment, who voiced him in the second film.
On January 27, Scott confirmed that Soul Archer, Bansha and Ghoultar will also appear in the film. Filming continued on February 9 to shoot a snow scene for the film. On February 19, Ryan Bowman, who voiced Kai and Vladimir in the first and second films, was dropped from the film's cast after being expelled from Scott's films. Kai was set to be recast, while the status of Vladimir's character was left unclear. On March 12, Scott confirmed that the film's script is on the verge of completion. On March 13, it was confirmed that the role of Vladimir Dubrovky will be cut from the film due to Ryan Bowman's expulsion. The film's script was officially completed on March 14. Filming also took place on March 18 and 19 to complete the film's snow scenes. Also on March 19, Charlie Hopkinson, a popular voice actor/impersonator and YouTuber, was cast in the role of Ford. The same day, the film's teaser trailer was released; it gained 1,300 views within three days of its release.
On March 22, Scott confirmed that the character of Hibiki was cut from the film's script during the revisions process. Hibiki was set to be Ronin's right-hand man in the film; the role was not cast before the character was cut. On March 26, Lego Zebra was officially cast as Griffin Turner and Cyrus Borg. On March 31, JumboGauge was cast in the role of Brandt, a trooper allied with Delmar and his team. On April 2, Luna Fett was cast in the role of Nya. On April 3, the role of Kai was officially recast, as Matt Howell was confirmed to be voicing the character. Filming continued into April, though the schedule was very tight.
On April 21, Scott confirmed that 1P Entertainment was recast in the role of The Overlord, supplanting Rob O'Dwyer in the role. Scott stated that he loved O'Dwyer's work on the part, but ultimately felt the need to bring 1P Entertainment back so as to create a sense of continuity with the character. On April 22, Joe Newman was confirmed to be voicing Zoltar, Zugu, Soul Archer and Ghoultar in the film. On July 18, JobbytheHong, a satirical toy reviewer on YouTube, was cast as Kapau and Chope. Scott had found Jobby's channel only a few weeks before casting him. Realizing that his voice would fit the characters perfectly, he proposed the roles to Jobby, who auditioned and got both parts.
Filming continued into September, though the schedule was still strict due to Scott's time in college. The same month, Brent Miller recorded his lines for the project. Filming also continued into October 2017, by which point filming was well over halfway complete. Upon the release of the film's first TV spot, it was confirmed that Captain Soto will return for the film, and that JTH Studios will reprise the role. Filming would also take place on November 21, with the official trailer being released on November 22. On November 23, Daniel Poulter expressed uncertainty about returning to voice Lucas and Snike, as he no longer has a mic, but Scott told him to record with a camera instead. Daniel is very busy and thus may record his lines sooner than others.
The film will feature music by Jay Vincent and Michael Kramer, the composers of the Ninjago TV show. Scott says that their works will have a tremendous presence in the film, which was made possible by the fact that Jay and Michael have released so much music in the year and a half since the second film's release.
- On July 16, Scott slipped in mud and dropped one of the LEGO models being used for the scene; it set shattered apart and he was unable to put it back together. Despite this, he still managed to use it in the scene, though details on this are unrevealed to prevent spoilers.
- Later that afternoon, one of the lenses in Scott's glasses popped out, and he lost a screw that held them in. Since he was three quarters of the way through filming the scene, Scott opted to finish filming by keeping one of his eyes closed in order to preserve his vision and see what was being filmed. He was successful in completing the scene, and his glasses were also fixed.
- On September 3, Scott was filming a scene on a fallen tree with a long, thin crack running across it. While filming, the Garmadon minifigure slid into the crack and was lost, and Scott couldn't reach in to get the minifigure. Several hours later, he used an axe to slightly open the tree, which allowed him to stick a twig inside and pull the minifigure up enough to reclaim it. The scene was completed the next day.
- On September 4, a group of kids found the set for Jamanakai Village and wrecked it, leaving everything covered in mud, wood all over the place, and the giant electrical barrel pushed into the creek. Scott was initially unsure of how or when he would fix the damage, given that he's busy with college and has little time in the first place. Scott has filmed many scenes since then, and later found the time to clean the set on October 28. Scott began filming on the set in November without any issues.
- Scott had filmed (and completed) two major scenes at a reservoir that was overgrown with cattails. The location briefly appeared at the very beginning of the first film and he decided to bring it back as a location in this one. On October 7, he found that all the cattails were removed from the reservoir and replaced with a large expanse of hay, which had happened sometime in the last two weeks. The reservoir was overgrown and, after several years of being in that condition, cleared out entirely. Nevertheless, the scenes at this location were completed the previous month, and filming for that day continued as planned.
- On October 28, Scott found that the set for the Slither Pit had sustained damage over the last few months. A small tree had collapsed over part of the ravine, while the wooden bridge running over the pit is rather unstable, as it wore out over time. Scott still intends to film in this location, and will likely leave much of the damage as it is.
- While fixing the Jamanakai Village set on October 28, 2017, Scott recovered several K'NEX pieces from the electric tower in Rise of the Great Devourer - two years after filming the structure's collapse in October 2015. Scott found part of the tower's platform and the red gear that held the chain up at the top of the tower.
- 1tjmac12, who voiced Garmadon, The Overlord and Pythor in the previous film, reprises the roles for this film. In September 2017, he changed his username to 1P Entertainment, and will thus be credited as such.
- The Garmadon minifigure used in the film was almost lost when Scott dropped it through a thin crevice in a fallen tree. He managed to reclaim it several hours later. This almost marked the first time where a minifigure was lost in a Ninjago film's production.
- Jack Morris, OonieandCacola, Westificationful and JTH Studios, who voice Cole, Jay, Zane and Lloyd, respectively, have appeared in all three of the series' installments. Originally, Cole and Lloyd had different voice actors before the first film was released, but the roles were recast for the project before filming began.
- GreshLord and CharCharStudios101 voiced Zane and Kai, respectively, in the first two parts of Ninjago, but the roles were later recast, with Westificationful voicing Zane and Ryan Bowman voicing Kai. Ryan was set to voice Kai in the third film, but was dropped from the cast and replaced with Matt Howell.
- The character of Hibiki was originally set to be in the film. Hibiki was a character from the Ninjago: Shadow of Ronin video game, which was confirmed to be non-canon to the main Ninjago storyline. Despite this, Scott still chose to adapt the character and depict him as Ronin's right-hand man, but ultimately cut him from the script due to his lack of purpose in the story.
- Joe Newman, who voices major characters Clouse and Cryptor in the film, recommended Rob O'Dwyer to Scott. Rob would be cast as Master Chen. Joe also recommended YamatoGuru to Scott, and in turn he would be cast as Morro.
- Scott has confirmed that Sensei Wu will still be called Sensei Wu throughout the film. For cultural reasons, in the TV show the character is referred to as "Master Wu" starting with "Day of the Departed" and "The Hands of Time". Scott doesn't find the title offensive, believing that Sensei Wu is a just character with strong morals.
- Vladimir Dubrovky, the Russian soldier seen in the first two films, will not return for this film due to Ryan Bowman's expulsion. However, the soldiers that he led in the previous installments will return.
