> If you consider yourself having more sophisticated, artistic taste in movies, you may reserve the term 'film' for those. For the movie snob, Casablanca is a film, Spiderman 4 is a movie.

I had no idea this was a distinction. I just thought 'film' was what the British called them and 'movie' was the Americanism. We say 'I'm going to the see a film' rather than 'going to see a movie'.
