A great movie by the man who brought you the monty python movies, Terry Gilliam. This movie depicts a society run purely through bureaucracy. The main character finds a flaw which has occured in the system, and sets out to fix it.
Gilliam's masterpiece, I really cannot overstate how great this movie is. Go see it as soon as you get the chance, and watch dreamworlds collide with reality in a tale of love and fear and a nightmare world of cogs and machines.
