* TheOtherMarty: Creator/QuintonFlynn was originally brought in to record Casey Jones's lines, but he was replaced by Creator/ChrisEvans for the final release.

* 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. Franchise creators Peter Laird and Kevin Eastman 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.

* VoicesInOneRoom: All of the turtles' voice actors were recorded together during production, which is helped by them being veteran voice actors.

** 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. Another story idea 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.
*** Munroe’s second film would’ve specifically featured Mikey joining the Foot, while the movie also would’ve loosely adapted the “City at War” arc. Meanwhile, the other Turtles and their allies traveled to Japan where they met Karai and the returned Shredder.
*** 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.

* FlipFlopOfGod: Nobody involved with production can really seem to agree whether or not it truly is a continuation of the first three films, some having said it takes place in a separate continuity, and some saying it takes place after the first three films in BroadStrokes. The comic book prequel seems to put it in an AlternateContinuity, but even then, it's unknown if the filmmakers even put it into account.
