In an intro to network security course, I showed both Sneakers and Swordfish to compare and contrast how Hollywood portrays hackers/crackers/computers/etc.

After each 'sneak' (the bank, the university lab, the toy company) in Sneakers, I pause and we discuss the techniques used. What I like about Sneakers is the way that most of their work is done through social engineering. I make sure to point out where they fall down on the subject of crypto. In general, though, it's about the best portrayal of hacking/cracking I've seen in a major commercial movie.

As for Swordfish - Now that you mention it, this movie bothers me more these days with the current administration than it used to. However, despite my reservations about Travolta's character, he does a very good job portraying the amoral zealot Gabriel.
