I liked the movie hackers when I was a kid and first came out with Jolie and everything but it's kinda ridiculous and the approach is very hollywood-esque.
I found Sneakers to be a great movie.
War Games was kinda old to get me involved when I first saw it. Tr0n is unwatchable (at least the latest version).
I like the matrix (imho best karate one-on-one fighting scenes ever made to date) for a variety of reasons and of course for the ssh root exploit and nmap.
Any other movies we should know of? Is this one any good actually?
Reboot from 2012 is a short film that features a whole lot of real world penetration testing tools and security lingo, but was overall poorly executed and nonsensical. Still worth a look just to spot all the references.
Antitrust is a programmer film. It's somewhat slow-paced and mediocre, but it has a nice scene with the Unix shell and overall tries to mimic the work environment at Microsoft.
Takedown, which although not that good, is a watchable telling of the Kevin Mitnick saga.
Travelling Salesman is based on computer scientists solving P = NP and creating a crypto weapon for use by the U.S. government. Actually quite intellectual, much like Primer.
That's all I can think of right now.
The Internship (2013)
http://www.imdb.com/title/tt2234155/Good and funny movie, and realistic (if you don't mind the Google logo everywhere)
Antitrust (2001, also known as "Startup")
http://www.imdb.com/title/tt0218817/Good movie that shows some C, Java and HTML code and also explains "open source". Miguel de Icaza helped them, so you see GNU/Linux desktops and GNOME shell and bash.
Most of the time in other hollywood films, it's downright bogus. [2]

It is on archive.org too: https://archive.org/details/haxxxor_volume_1_dvd
Not surprising, considering that the movie is most likely about penetration.
