Ninjago: Rise of the Great Devourer

Ninjago: Age of the Golden Master is an upcoming live-action LEGO film featuring the LEGO Ninjago characters. The film will be written, directed, filmed and edited by Scott Pincus and distributed by Bio-Builder Productions. It is the second sequel to the 2014 film Ninjago, the sequel to Rise of the Great Devourer, and the final installment in the series. The film will star returning cast members Jack Morris, Ackar Productions, OonieandCacola, Westificationful, JTH Studios, FireStar97Studios, 1P Entertainment and others, and introduces Lance Newman, YamatoGuru, JobbytheHong, Matt HowellLuna Fett and Brent Miller, the original voice of Zane

Set two years after the second film, Pythor has formed an alliance of villains and seeks to fulfill the prophecy of the Golden Master - an all-powerful being bent on razing Ninjago. The Ninja and their allies face the deadly conflict to save Ninjago from an age of destruction. Progress on the film picked up in 2016, but was slowed due to the production of Creepy Guy 4 and other projects, as well as Scott's graduation of high school and transition to college. The film draws elements from seasons three through six of the TV show. Filming for the project is over halfway complete, and editing is currently underway. The film is set to start airing on July 19, 2018. 


Two years after the second film, Pythor 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. 


Cast members with an * next to their name switched their username following the release of the second film.

New AntagonistsEdit

  • JobbytheHong voices Master Chen, the leader of a criminal empire that worships the Anacondrai. He serves as one of the film's main antagonists. Rob O'Dwyer was cast as Chen in December 2016, but resigned in April 2018 due to obligations with other projects. Jobby was recast in the role that June.

  • Lance Newman voices Soul Archer, a ghost from the Cursed Realm who escapes with Morro. 
  • Lance Newman voices Flintlocke, a high-ranking Sky Pirate who was second-in-command under Nadakhan. 

Additionally, JobbytheHong will voice Kapau and Chope, two of Master Chen's cultists who are good friends. Lance Newman will voice Ghoultar, a ghost from the Cursed Realm who escapes with Morro. The Sky Pirates Dogshank, Clancee and Doubloon will also debut, along with Krazi, the Skulkin warrior of lightning, and Bansha, a ghost from the Cursed Realm. None of these characters will have voice actors. Various Nindroids, Anacondrai Cultists and ghosts are set to appear in the film.

New ProtagonistsEdit

  • Lance Newman voices Ronin, a mercenary and bounty hunter who operates out of the city of Stiix. 
  • Lego Zebra voices Griffin Turner, the Elemental Master of Speed and a close ally of Karlof. 
  • Lance Newman voices Karlof, the Elemental Master of Metal and a close ally of Griffin Turner. 
  • Ford, an old war hero who is a member of Delmar's team. Scott approached Charlie Hopkinson, a popular voice impressionist on YouTube, to take on the role - but later opted to find another actor for the part. 
  • Lance Newman voices Zoltar, a soldier in the Venomari Tribe who defected and allied with Delmar's team. 
  • Brent Miller voices Brent, a young man and a member of Delmar's team. Brent Miller voices Zane in the Ninjago TV show, and was cast in Age of the Golden Master in September 2016 after Scott won his voice actor contest. 

Additionally, Lego Zebra will voice Cyrus Borg, the founder of Borg Industries who has a minor role in the film. JumboGauge will voice Brandt, a trooper and member of Delmar's team. Various troopers allied with Delmar are set to debut in the film, although their names are currently unconfirmed. JobbytheHong, who will debut as Kapau and Chope in the film, is set to have vocal cameos as several miscellaneous characters.


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. In the time since, the Bounty has been entirely rebuilt, with a far more advanced design. The vehicle was custom-built by Scott to resemble its appearance in season four and beyond. It is the only one of the Ninjas' vehicles from the previous films that is confirmed to return for this installment.
  • Roto Jet - A jet bomber with a series of laser blasters at the front of it. The Roto Jet has enough firepower to swiftly take out many ground adversaries and their vehicles; the vehicle is flown by Cole. 
  • Proto Sam-X - Also known as "Nya's car"; a small all-terrain vehicle equipped with a large missile launcher. 
  • D.B. Express - Also known as the "DB X"; a large fortified vehicle built to transport weapons and allies in harsh climates or situations. It is often used by the Ninja, especially when Destiny's Bounty was not in service. 
  • Bladecopter - A large stone-built jet designed by the Anacondrai Cultists. Loosely inspired by the Serpentine's Rattlecopters, the cultists produced numerous Bladecopters as a means of swiftly traversing Ninjago's vast jungles. 
  • Condrai Crusher - A stone-built vehicle with a snake-like head and spinning stone blades, also designed by the Anacondrai Cultists. The Crushers are able to quickly clear an area of debris and adversaries, cutting through anything in their paths. 
  • Jungle Raider - A stone-built all-terrain buggy, also designed by the Anacondrai Cultists. Faster than Condrai Crushers, the Jungle Raider's suspension system, large tires, and overall small and compact build allow it to zoom through Ninjago's jungles with ease. 
  • 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 that point, Ninjago only had two seasons and the lore wasn't as expansive as it would be three years later. Many of the concepts he developed were scrapped as time went on, although a select few made it to the official script. 

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 (later known as Ackar Productions) was confirmed to reprise his role as Sensei Wu. A month later, on August 6, 1P Entertainment (formerly 1tjmac12) was confirmed to be reprising his roles as Garmadon and Pythor in the film. A casting call for the film officially began on YouTube on August 8. 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, Lance Newman was confirmed to have joined the film's cast as Clouse, Cryptor, Karlof and Flintlocke. On December 1, NinjaBoys, now known as TheOnlyVie, was confirmed to be returning as Lizaru, Spitta and Bytar from the second film. On December 28, YamatoGuru was cast as Morro. On December 29, Ryan Bowman was confirmed to be returning as Kai and Vladimir for the film. Ryan was technically 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.

Scriptwriting/New RolesEdit

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, Lance 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. 

On January 12, 2018, Scott expressed his uncertainty over Collector1100 reprising his role as Dareth, as he hadn't contacted him in a few months. On January 25, Scott finally made contact with Collector, who said he "isn't really interested" in reprising his role as Dareth in the film. Scott tried convincing him to return for the film, although he ignored most of Scott's requests. On February 4, a TV spot/'Super Bowl trailer' was released for the film. On February 15, Westificationful was cast as Eyezor and Wrayth in the film. On February 18, Scott received from Garnettfox and JobbytheHong that they're still part of the cast, as Scott hadn't managed to contact them for several months. On April 5, Scott officially sent out the lines for the film's entire cast. On April 11, Rob O'Dwyer resigned from the film's cast, due to an overwhelming number of other projects he's working on. For the next two months, Scott searched for a new actor for the role.

In early June, Scott began clearing out overgrown plants in the set for Jamanakai Village, as he prepared to resume and wrap filming over the summer. On June 20, JobbytheHong was officially cast as Master Chen. He replaces Rob O'Dwyer after he resigned from the role on April 11. On June 29, it was confirmed that the film will begin airing in July 2018; an exact release date has yet to be determined, although this is the closest it's been to being confirmed. On July 9, JobbytheHong completed his lines for Master Chen. On July 10, Daniel Poulter completed his lines for Lucas and Snike, and Lego Zebra completed his lines for Cyrus Borg and Griffin Turner. The same day, R&D, a popular Ninjago YouTuber, was officially cast as Dareth - replacing Collector1100, who resigned from the role in January. On July 13, the film's release date was officially confirmed as July 19, 2018; a TV Spot making the announcement also came out that day. On July 17, a thunderstorm shut down Scott's computer and corrupted his Final Cut Pro library, nearly wiping out Part 1 of the film. Fortunately, Scott was able to recover a backup of Part 1, though he had to recover the source files; ultimately, it suffered only minor damage. 


The film will predominantly 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 much music in the time since the second film's completion in March 2016. In the time since, Scott has also realized the significance of the series' music, which inspired him to incorporate it more into the film. The scores from seasons one to five of the TV show will be heavily featured in the film. Themes for characters such as Cryptor, Chen, his cultists, and Morro will all be introduced and heavily featured.

Music by Steve Jablonsky and Hans Zimmer will also be used in the film, although Scott says the film will have a much heavier focus on Jay and Michael's scores. He feels their scores were underused in the previous films, and wants to devote much more attention to them in this installment. 

Filming IncidentsEdit

  • On July 16, 2017, 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 lens in Scott's glasses popped out, and he lost a screw that held them in. Since he was deep in the woods, as well as 3/4 of the way through filming the scene, Scott opted to finish filming by keeping one of his eyes closed 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 was busy with college and had little time in the first place. Scott 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 beginning of the first film and it returns in this film. On October 7, he found that all the cattails were removed and replaced with a large expanse of hay, which happened sometime in the last two weeks. The reservoir was overgrown and, after several years, cleared out entirely. Nevertheless, the scenes there 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 filmed at the location, and left much of the damage as it was. 
  • On July 3, 2018, a severe thunderstorm hit the area where the film is shot. Heavy winds and rain knocked over many trees. A giant tree, which had partly toppled due to Hurricane Sandy years earlier, collapsed. It fell in front of Jamanakai's entrance (where the Ninjas' tree base used to be), smothering it with dense foliage and branches. Scott has spent several days cutting through the foliage, which he says won't have an impact on filming. 


  • The film is set to begin airing in July 2018 - continuing a trend set by the previous films, as the first film began airing in July 2014 and the second in July 2015. Scott says this trend is actually coincidental. 
  • Collector1100 was set to return as Dareth in this film, but in January 2018, he resigned from the cast due to a lack of interest. Five months later, Scott is still looking to recast the role. YamatoGuru, who voices Morro, is a frontrunner for the part. 
  • In casting the film's new main villains - Chen, Morro, Clouse and Cryptor, Scott looked to recreate their voices from the TV show. Many people auditioned for the roles, with YamatoGuru being cast as Morro and Lance Newman being cast as Clouse and Cryptor. JobbytheHong was later cast as Master Chen for his impersonation of the character. 
  • Various actors auditioned for Master Chen after Rob O'Dwyer's resigned from the role, including Sam Charbonneau and YamatoGuru, before JobbytheHong was cast in the role. Scott didn't expect Jobby to take an interest in the character, but was thrilled when he did and loved his audition. 
  • Joe Teddick, also known as Ackar Productions, returns to voice Sensei Wu. However, his voice will sound slightly different in the film. Joe kept elements of Wu's raspy voice, but made him sound younger and more clear. All in all, he maintained Wu's wise tone. Scott says that Wu's new voice is "somewhat different, but fits the character perfectly". 
  • Scott has stated that Pythor was the hardest minifigure to maneuver in this film. Due to the structure of Pythor's body, with the broad torso and long tail, it was hard to hold and maneuver him while making him "speak". The size of his neck posed an issue with capturing his body in the frame, as Scott had to hide his hand from the shot while trying to capture as much of the figure as possible.
  • Lance Newman will voice General Cryptor in the film. In the TV show, Richard Newman provided Cryptor's voice. The actors are not related, and their last names being the same is a coincidence.
  • Like the previous two films, Age of the Golden Master will be released on YouTube in separate parts.
  • Scott been preparing for the film since 2014, when he first began collecting sets for Rebooted.
  • Due to personal changes in his life, this will be Jack Morris's last time in which he voices Cole Hence, the series' main protagonist.
  • As shown in the film's trailers, the Ninja will wear their Tournament, Deepstone and Destiny (season six) robes at some point in the film.
  • Lloyd is set to keep his original head mold in the film, which appeared in the sets for season one. In the season three sets and beyond, Lloyd gained a new head mold that bears little resemblance to his appearance in the TV show. Scott kept the original head mold as he didn't want to create such a big and unnecessary change.
  • The film is set to have over forty characters with different voices - exceeding the voice cast of the second film, which had around thirty-six voiced characters.
  • ToaGresh300, Ryan Bowman, Collector1100 and Russell Parkinson, who appeared in the first two films, and Abby Pincus, who appeared in the second film, will not return for this installment. Ryan and Collector1100 were initially confirmed to return, but were later dropped from the cast. 
  • With the release of this film, Jack Morris, Ackar ProductionsWestificationful, OonieandCacola, JTH Studios, FireStar97StudiosBio21 and Cameron Morris will have appeared in all three films of the series. 
  • Garnettfox, Daniel Poulter and 1P Entertainment, all of whom debuted in the second film, are set to return for this installment.
  • 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. 
  • 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. 
  • 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 MorrisAckar Productions, OonieandCacola, Westificationful and JTH Studios, who voice Cole, Sensei Wu, 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. 
  • Lance Newman, who voices major characters Clouse and Cryptor in the film, recommended Rob O'Dwyer to Scott. Rob would be cast as Master Chen, though he later resigned from the role in April 2018 due to obligations with other projects. Lance 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 or stereotypical, believing that Sensei Wu is a just character with strong morals.
