Equilibrium is one of the best movies you've never heard of.

Ok so it's a bit on the cheesy b-movie side, as far as graphics and effects. But it's a fun movie, that makes a point. It's about human nature, freedom of thought, emotion, passion, war.

It's like Fahrenheit 451 meets the Matrix, throw in some 1984. And yes, I've read Bradbury and Orwell.
