However, I have many a favorite movie. I'm a bit of an addict, actually, and will probably have to do favorites by genre. My embarrassingly large dvd collection is organized alphabetically by genre, actually. Also, bear in mind that these are favorites of the moment.
Action: Inglorious Basterds
Period Piece: Pride and Prejudice
Contemporary: No favorite
Musicals: Hairspray. Or Sweeney Todd
Indie: All of the above. Except I Heart Huckabees. What a piece of crap.
