** Creator/TwentiethCenturyFox initially planned to distribute the film, but after Barry Diller succeeded Leonard Goldberg as CEO, those plans fell through.
** Originally, Steve Barron wished to replicate April O'Neil's jumpsuit look from the early Mirage comics and the 1987 series. The look was going to closer resemble the cartoon with a yellow colored jumpsuit and a big head of red hair (as opposed to a green jumpsuit and brown hair). However, Judith Hoag found the jumpsuit "horrifying" and the idea was nixed in favor of a yellow raincoat.

** Splinter's puppeteer Kevin Clash and Leonardo's facial puppeteer Martin P. Robinson worked on ''Series/SesameStreet''.

* ThrowItIn: The reason why Raph has a Brooklyn accent in so many other adaptations is because Josh Pais (his actor in the first film) had a thick accent himself and the filmmakers decided it was [[BrooklynRage just too perfect]].

The yellow raincoat April wears in the beginning of the movie is a homage to the yellow jumpsuit she wears in the 1987 cartoon.

** Tatsu brutally beats a young Foot ninja named Shinsho due to the Foot Clan's failure. Originally, Shinsho was intended to die, but that scene was cut since it was considered too violent for some. The dialogue was replaced with the kid comforting him saying "you'll be alright," to show Tatsu only injured him.
*** In the junior novelization that was done of the movie, Shinsho ''does'' die. Novelizations of movies are typically based on the screenplay, so the change must have happened solely in the editing room.
*** In the French version of the movie, Shinsho does die.
** In the 1980s, the first pitch Eastman and Laird got for a film treatment was from schlockmeister Creator/RogerCorman's New World Pictures. The idea was to have the Turtles played by four comedians who were popular at the time - Creator/{{Gallagher}}, Creator/SamKinison, Creator/BobcatGoldthwait and Creator/BillyCrystal. The actors would be dressed in turtle shells and have their arms and legs painted green. Another treatment received at the time took the Turtles into R-rated territory and included a scene with partially nude nuns on roller skates fighting the heroes. It was turned down, but Peter Laird has admitted to wondering how different things would be if he had accepted at the time.
