History Trivia / TMNT

* StudioHop: While the first three films were released by Creator/NewLineCinema, this film was distributed by Creator/WarnerBros Pictures.

*** Munroe’s third film would’ve introduced the Triceratons as well as the Technodrome and Dimension X. Munroe’s first pick to play Commander Mozar was Creator/MichaelClarkeDuncan.

* RealLifeRelative: In the Latin American Spanish dub produced by Warner Bros.:
** Gloria Rocha is the ADR Director and her brother Abel provided additional voices.
** Creator/JesusBarrero voiced Leonardo and his nephew Víctor Covarrubias provided additional voices.
** Rodrigo Carralero (Donatello) is the son of Juan Alfonso Carralero (Max Winters).

** Creator/{{Mako}} reportedly did not complete all of his recording for Splinter [[AuthorExistenceFailure before passing away of cancer]]; Greg Baldwin can be heard delivering some of Splinter's lines to sharp-eared listeners.

* DeletedScene: There was another ending made which featured Raphael giving Casey Jones his bike, as well as another scene featuring Michelangelo giving Splinter a piece of cake from a birthday party he was working at. The latter was changed due to the filmmakers believing introducing Splinter in a comical scene would’ve been a disrespectful way to introduce him.

* TheOtherDarrin: Creator/{{Mako}} reportedly did not complete all of his recording for Splinter [[AuthorExistenceFailure before passing away of cancer]]; Greg Baldwin can be heard delivering some of Splinter's lines to sharp-eared listeners.

* ThrowItIn: The song Splinter cheerfully sings at breakfast is an old Japanese song Mako himself enjoyed singing that found its way into the film.

* AuthorExistenceFailure: ''TMNT'' was Mako's last film role before he died of cancer during production, so Greg Baldwin, who already had experience voicing [[WesternAnimation/AvatarTheLastAirbender Iroh]], another one of Mako's characters, provided Splinter's remaining dialogue.

* DeletedScene: There was another ending made which featured Raphael giving Casey Jones his bike, as well as another scene featuring Michelangelo giving Splinter a piece of cake from a birthday party he was working at.

** As shown in [[https://m.youtube.com/watch?v=qhMYDst0hxY this video]], the movie was originally going to have just voice actors until ExecutiveMeddling kicked in, resulting in some celebrity casting. The creators were able to step in and get the turtles and most of the supporting characters to be played by professional voice actors.

** In the Japanese dub, the main cast from the 2003 series reprise their roles again, including Creator/TetsuyaKakihara as Leonardo, Anri Katsu as Michelangelo, Creator/YujiUeda as Donatello, Eiji Miyashita as Raphael, Shoto Kashii as Splinter, Yuko Kato as April, Tokuyoshi Fukushima as Casey, and Ryoko Gi as Karai.

** Kevin Munroe stated that he would have liked to do a sequel, either featuring the Foot Clan (which, given Karai's ominous remark at the end of the film, [[spoiler: indicated that the Shredder might have come back]]), the Rat King, or the Triceratons. Also according to a concept poster for the unmade sequel, It would have centered around Michelangelo with his brothers and master being demutated, Also some story ideas would have Mikey joining the Foot Clan wearing a black mask to be taken more seriously by the other turtles. Munroe also expressed interest in having Sarah Michelle Gellar and Chris Evans reprise their roles as April and Casey in a live-action film.
** Originally the backstory of Yaotyl and the Generals was going to be told by Winters when April and Casey deliver Aguila's statue to him, but the filmmakers decided to just get everyone on the front page in the film's prologue.

The creators stepped in and got the turtles and most of the supporting characters to be played by professional voice actors.

* StillbornFranchise: An odd case where it did well enough for a sequel to start being made, but it ended up not happening. We can attribute this to a combination of said sequel having issues with DevelopmentHell, Peter Laird selling the whole franchise to Creator/{{Nickelodeon}} in 2009, and Imagi Animation Studios shutting down after their ''WesternAnimation/AstroBoy'' film ended up being a BoxOfficeBomb the very same year.

** Rodrigo Carralero (Donatello) is the son of Juan Alfonso Carralero (Winter).

* InMemoriam: The film is in memory of both Creator/{{Mako}} and Man Kit Cheung(German Cheung) who both died in 2006.

** Creator/JesusBarrero voiced Leonarrdo and his nephew Víctor Covarrubias provided additional voices.

* ThrowItIn: The song Splinter cheerfully sings at breakfast is an old Japanese song Mako himself enjoyed singing that found its' way into the film.

** In an earlier draft that found its' way into tie-in materials, Yaotyl and the Generals would've succeeded in destroying the ancient civilization we see them attacking in the prologue, but they would've been cursed with immortality and being turned to stone by a sorceress from the civilization who was not present at the battle.

** While the tie-in game [[RoleReprisal does bring back]] the voices for the turtles, Splinter and Max are instead voiced by Montreal-based actors Terrence Scammell and Mark Camacho respectively. For the other game that uses this style, ''VideoGame/TeenageMutantNinjaTurtlesSmashUp'', the concurrent voice cast of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]] also return to their respective roles.

* RealLifeRelative: Real-life siblings Gloria and Abel Rocha were involved in Warner's Latin American Spanish dub. Gloria directed the dub while Abel provided additional voices.

* CreatorBacklash: Creator/JamesArnoldTaylor didn't approve of the celebrities voicing in the movie, with the exception of Creator/PatrickStewart.

* ExecutiveMeddling: The reason Creator/PatrickStewart, Creator/ChrisEvans, and Creator/SarahMichelleGellar were in the movie was because the studio thought the film didn't have enough star power. Peter Laird and Kevin Eastmen, the co-creators of the franchise, stepped in and told them to keep the Turtles actors as-is, as they wanted the Turtles to be recognized as the characters and not the actors.
