we will never know what he said to her. at least thats what the director intended it to be. its brilliant.
btw, that last scene where bob chased charlotte on the street, there wasnt supposed to be a kissing scene.
The kiss between Bill Murray and Scarlett Johansson at the end of the movie was not in the script, but was an "in the moment" ad-lib between the performers.
cool eh? hehehe. got that from the trivia page of LiT on www.imdb.com
