In the Australian version, the voices of the Watches ("Don't Buy Us We're Fakes") in the train station, were dubbed by 6 kids who had won a competition to appear in the movie. A voice coach trained them to speak with an American accent to blend in with the rest of the movie.
In the Mexican version, at the end credits the song that plays is "Un Héroe Real" (A Real Hero) sung and composed by Aleks Syntek. The lyrics say at one point (translated from Spanish): "I want to be more than a robot, capable of loving and dreaming. I want to be more than a robot, a real hero not a fiction one".
