Looks like the server has been Dugg to death, but here's the list, and the Digg article:
The Truman Show (1998)
I Heart Huckabees (2004)
Waking Life (2001)
The Matrix (1999)
Dark City (1998)
American Beauty (1999)
Fight Club (1999)
Donnie Darko (2001)
I've seen Network, American Beauty and Brazil.
I don't remember much about Network, except that I liked it. I saw it a loooong time ago.
I thought American Beauty was ok, but it didn't come anywhere near living up to all the hype.
Brazil is my absolute all-time favourite movie. If you haven't seen it, you should.
