Deliberate mistake: In the hotel bar at night, when Edward is playing the piano and Vivian goes to find him, after Edward has dismissed everyone else from the room Vivian sits on top of the piano and puts her feet on the keyboard. Her feet go onto the keys in the middle of the keyboard but the sound that comes out is from the bottom and the top notes of the piano.
Pretty Woman (1990)
1 deliberate mistake
Directed by: Garry Marshall
Starring: Julia Roberts, Richard Gere, Jason Alexander, Hector Elizondo, Ralph Bellamy, Laura San Giacomo, Amy Yasbeck
Continuity mistake: During the scene where Vivian is with Edward at the hotel room, they're talking while he's inside sitting and she's outside. You can see on the first shot it's day time and when Edward stands up and goes near her it's evening time already. (or viceversa)
Edward: What makes you think I am a lawyer?
Vivian: You have that sharp, useless look about you.
Trivia: Richard Gere actually plays the piano - and he composed this piece himself.
Question: Is there any particular reason Julia Robert's dress was changed from the blue and white dress she wears at the beginning of the movie to a black and pink version of the same dress on the movie poster and film/disc cover? I've always wondered why - there's really no reason for the change.
Chosen answer: Posters are usually designed long after the film has been made, and by the marketing department. Decisions about the outfit may have been based solely on what was considered best by the marketing department (for instance, to match the color of the lettering in the title.) Also, Julia Roberts' head has been super-imposed onto a model's body in the poster image (just as Richard Gere's hair has been darkened). These are all creative marketing decisions.
