Directed by: Adam Shankman
Starring: John Travolta, Christopher Walken, Michelle Pfeiffer, Queen Latifah, Zac Efron, Amanda Bynes, Nikki Blonsky
Revealing mistake: Right after "Without Love", we see Edna answering the phone. If you've seen the movie as many times as I have, you'll see that this is a recycled shot from earlier when Mr. Pinky calls.
Revealing mistake: During "You're Timeless To Me," It shows the house lights on. In the very end of the song, when Wilbur blows out the candle, it is pitch black, but the house lights should still be on.
Factual error: The movie is set in 1962, but when Tracy misses her bus, she catches a ride on an International-Harvester truck that wasn't introduced until 1969.
Edna: Don't worry. He'll figure out some day that he's crazy 'bout you.
Tracy: You have to say that. You're my mother.
Edna: Well, I know a little something about men.
Trivia: As for John Travolta playing Edna Turnblad, that goes back to John Waters having often cast 'Divine' in his movies. 'Harris Glenn Milstead' was an actor best known for performing in drag as 'Divine', John Waters cast him as Edna in the 1988 version. When the Broadway musical was being cast, they cast Harvey Fierstein as Edna Turnblad, and started a tradition of casting a man in the role of the mother, so the movie is just keeping that tradition going.
Question: Why is it that Tracy's hair keeps getting more and more highlights through scenes?
Chosen answer: It's common for filmmakers to subtly alter a character's appearance throughout the film to reflect how the character changes. In this case, as Tracy comes out of her shell, her personality becomes brighter, stronger, and more pronounced, and that is shown by her increasingly lighter hair.
Answer: I believe her hair is also symbolic of white and black integration.
