25 best hacking movies ever

WarGames (1983)

There are a couple of lessons to learn from WarGames. One: it would be a bad idea for America to hand over its Cold War missile defences to the whims of an "intelligent" computer. Two: if it did, it would be a good idea if the password wasn't a name so common you'd shudder if it crossed your mind to use it for your webmail. It's not hard to see where the suspenseful hacker plot goes from there.
