Trivia: Richard Gere actually plays the piano - and he composed this piece himself.
Trivia: The scene where Edward offers Viv the necklace and shuts the box on her fingers wasn't scripted - Richard Gere did it as a joke. You can tell because when he does it, Julia Roberts laughs and looks up and around (ie. at the film crew) - in the context of the scene there wasn't anyone there for her to look at. (01:21:45)
Trivia: Per Gessle (of the rock group Roxette) has said in interviews that he was asked to write a song for the film. However he didn't have the time so he gave the filmmakers an already recorded song, "It Must Have Been Love."
Trivia: On the movie poster, Edward's hair is brown. In the movie it's gray.
Trivia: In the shots of the city in the very beginning, you will notice that some of the neon letters in the hotel where Vivian lives are burned out. The only remaining lighted letters spell "HO," which is "hoe" (short for "whore") a slang term for a prostitute.
