as I promised, I have done an analysis of the differences between the book and the movie, posted it here. Sorry it looks quite a dissertation; I just wanted it to be as exhaustive as possible [for bears at the moment].

I dearly hope:

1. Brice will have a look, since it was mainly written as an answer to his question;

2. There'll be some discussion about Levin's novel here in The Book Club. It has been inactive for almost a year by now.
