Carter Burwell raconte comment lui est venir l'idée de la berceuse de Bella, joué par Rob dans Twilight. Le texte est en anglais je n'ai pas eu le temps de traduire

I came to Oregon to meet Catherine Hardwicke and see some of the film she was shooting, Twilight. She mentioned that the producing company, Summit Entertainment, had just requested that a new scene be added to the film. The scene existed in the novel but hadn’t originally been part of the screenplay (films are not one-to-one translations of books). In this scene Edward would play piano for Bella. I wasn’t officially working on the film at that point and they didn’t know what Rob Pattinson (Edward) should play during the shoot. This is not an unusual situation – many films have an actor sitting at a keyboard, swaying back and forth, pretending to play music that was only written after the film has been shot and edited. This case was unusual in that Rob is a fine musician, and fully capable of playing the piano or probably any other instrument.
