Trivia: Even though she did not win an Oscar for "Best Director," Sofia Coppola became the first American female director and the second female director to be nominated for that award. No woman had ever won "Best Director." Interesting enough, she was nominated nearly exactly a decade after the first female director (for "The Piano") was nominated.
Question: Do Charlotte and Bob end up sleeping together? While the obvious answer is no, when they are going up the elevator the night before Bob is leaving, notice the jacket he is wearing. It's the same jacket that Charlotte gives to him the next morning which he says she "stole" from him. While it doesn't necessarily say they did, they obviously did something together after the elevator scene.
