A group of people -- nine to be exact -- are trapped in a house. They are given instructions over an intercom, basically telling them that the last one who lives will receive five million dollars. From there on out, the house gets dangerous: will we see the best or the worst of human nature?
One could describe this movie as "Saw 2" meets "House on Haunted Hill", though that wouldn't really do this film justice. Others have compared it to "Battle Royale". Simply put, while the themes may overlap, this film is still unique in many ways. Which isn't always easy after a century of plots being used up.
Dennis Hopper has a fairly large role, but mysteriously he appears as a priest. Also, he talks slow and awkward like he can't remember his lines. I didn't really think this captured his ability very well. As another reviewer said, "Dennis Hopper is ineffective as a priest. If you're going to have Hopper in your movie; make the most of it, don't give him a role like this." There seemed to be little concern among the housemates that the food was poisoned. Or the booze. It is mentioned once, but I believe this is after they've already been eating and drinking.
The film has a weird soundtrack, which seems out of place (too pop rock for a horror film), and there's a strange hip-hop dance scene. I don't know what is up with that. But the film as a whole is good, and I have to say it has a great ending. I can't say what it is, of course, but if the film does not impress you, wait until the end because I think it really redeems itself of any flaws.
