Expert Reviews takes a look at the top ten things Hollywood thinks computers can do, you can read it over here. Here's the first one:
10. When systems go wrong, stuff starts to explode
When a computer crashes in real life it's often quite annoying, but spectacularly dull to watch. In films, when a computer goes wrong, it's very exciting and stuff starts to explode. The way computers go wrong depend on the film or TV show.
In Star Trek, Kirk need only ask an alien computer to "Explain. The. Human emotion. Known. As.....Love", for it to go into a bizarre loop where its logical systems can't computer and it explodes. In Star Wars Episode I: The Phantom Menace (one of the worst films ever made), the destruction of the main ship causes the droid army to lose its control signal and fail - one of them even has his head fall off. Quite why you'd ever build this feature into your army of destruction is beyond us.
Sparking and exploding control stations is our favourite. Thankfully this doesn't happen in real life - imagine your keyboard exploding just because Windows had crashed again.
