Trivia: At one point in the movie Shredder scolds Tatsu, and right after that, Tatsu curses saying, "kuso." That's about the equivalent of saying sh*t in Japanese.
Trivia: The four actors playing the Turtles also had cameo appearances in the movie without their costumes: Tilden (Donatello) was the Foot messenger that says "We've been looking for you, Miss O'Neil". Pais (Raphael) is the passenger in the taxi cab that says "What the heck was that?" Sisti (Michelangelo) is the pizza delivery man that can't find the Turtle's address. Foreman (Leonardo) plays a gang member in the warehouse when Casey Jones defeats Tatsu.
