The evolution of hackers in film...

[Requia ☣]

The Italian Job had a hacker (if I'm remembering the right movie at least).  Hacked into the traffic light system.

[Rumckle]

There was also a couple of hackers in the Transformers film.

[Bruno]

The original April O'Neil from TMNT was kind of a hacker.

In later versions, she was a reporter.


edit: that's not really a film example, though.

[Lies]

Office Space

[Prince Glittersnatch III]

In any movie containing a hacker but not explicitly being about hacking said hacker could easily be replaced with a wizard and the plot would still work.

Case-in-point, Die Hard 4.0. Hacker(wizard) uses m4d haxX0r sk1llz(Magic) to override the pilots targeting system(hex the pilot) causing him to attack the protagonist.

Also to keep the thread from derailing:

I an Number Four. All aliens are experts at hacking computers.

EDIT: One of the characters can hack in to Facebook but cant "get through the firewall" of some shitty Geocities conspiracy site.

Speaking of aliens, Independence Day.

[Lyris_Nymphetamine]

Jurassic Park - because DNA hacking counts too.
