If you like the matrix and martial arts films like Kill Bill Vol1, rent the DVD Equilibirium, heck go and buy it. That DVD was the first one that I saw the Kill Bill preview on, and it totally fits the main feature too. The coolest thing about Equilibrium is that the director/writer invened a new martial art style that takes firearms beyond anything even the hong-kong guys have done, he calls it "gun-kata." The scenes with the characters performing gun-kata are just mezmerizing - kind of like when the matrix came out and their 3d rotational slow-mo was so new and such an intriguing special effect. The story in Equilibrium ain't bad either, kind of a retelling of farenheit 451 - nothing awe-insprining but pretty solid and expertly executed.
If you are wondering why you never saw Equilibrium in the theaters it is because the studio made a profit by selling foreign distribution rights for more than it cost to make the movie. So rather than "risk" it at the box office, they showed it for a couple of weeks in a couple of markets and then took it out of domestic circulation because they preferred to take the $5M or so in profits from the foreign distribution rights and leave it at that rather than pay for a promo campaign and making enough prints for a widespread distribution. But in other countries Equilibrium easily hit the top ten charts, last I heard, a year after domestic release, it was #1 in Thailand.
