This doesn't appear to be so much a curated list of much-watch movies so much as a list of all movies about hacking ever. Here is my curated list of movies ever hacker and cyberpunk enthusiast must watch: * Sneakers * Ghost in the Shell * Tron Why is Tron there? Because the screenwriter loosely based the character around her husband. Who was her husband? Alan Kay. Tron's protagonist is Alan Kay.
I'm very pleased to see a comment repping Sneakers on the top of the pile. A highly underrated true hacker classic! Ghost in the Shell rather than Patlabor?
And Sneakers, asides from the magic, encryption-breaking MacGuffin, is some of the most realistic hacking in movies. What's the preferred tactic of these tech geniuses? Basic social engineering. Sure, they know a lot of other tricks, but why figure out a clever way through the badge system if a cake and some birthday balloons will work just as well?
