Sadly, it's kind of hard for me to come up with good hacker movies, but I can at least try to make a recommendation of interest to (most) hackers: Paprika. It's an anime film (by the same team that brought us Perfect Blue and Millennium Actress) that explores the ramifications of a device that allows someone to interact with someone else's dreams. Like I said, not a hacker movie per se, but I think it's one that most hackers will probably like.
