Sneakers - one of the best computer movies when I was a kid. I used to watch it over and over again. Good times. Must go find it somewhere. That movie probably had an impact on actually getting into the business later on.
I loved this movie and I still watch it a few times a month as I am working on other things. Sometimes listening to movies provides me more focus than random music from my playlists.
I'm the same way - for me, "Bladerunner", "Barbarella" and "Flash Gordon" are on auto-repeat as my background noise for serious coding sessions. For some reason these 3 movies just work so well in that sense ..
