The 9 worst tech movies of all time

Sometimes terrible movies -- the ones with such bad acting, dumb dialogue and cheesy special effects that they're unintentionally hilarious -- are the ones we remember the most. No genre is immune, but movies about technology -- ominous Web sites, evil hackers and so on -- seem to fail more often than not. Maybe that's because it's hard to dramatize someone sitting at a computer. Maybe it's because Hollywood doesn't understand tech.

So that got us thinking about the worst tech movies ever made. Not science fiction movies, with their planet-killing asteroids, journeys to the Earth's center, and homicidal dinosaurs, but movies about the digital world. Movies with technology that, even by Hollywood standards, is ridiculous.

For help, we enlisted some people who either know about movies or technology or both: Steven James Snyder, a film critic for Time magazine's Techland; Matt Atchity, the editor-in-chief of Rotten Tomatoes, the movie site; and Sidney Perkowitz, a physicist at Emory University and the author of "Hollywood Science: Movies, Science and the end of the World."
