I think it might me a British horror film. But I think there was this young American actress in it (I thought it was Ali Larter, but I didn't see it listed on her Wikipedia page). There are a group of people that think they are going to be on a reality show or something. They are locked in this room together and only given a small amount of food. Then they are instructed that no one can leave until they start killing each other. When there is only one person left alive the doors open up and they find a duffel bag full of money, they think they're leaving but find that they are in a room with a whole other group of people, all holding on to a duffel bag of money.

Okay I know that's really vauge but I watched this movie a couple years ago on like showtime or something and I cannot for the life of me figure out what the name of it was. Anyone??

i am eagering to find the name out and buy it on www.dvdsetshop.com.

Man, I wish somebody would tell you the name of this movie because I'm really curious!

But I have no idea what it is.

I love a good horror film, but I have no idea on this one.

The movie you are talking about might be called House of 9. And the actress is Julian Davis, who resembles Ali Larter. Not sure if this is what your looking for but, it is similar to what you described. http://en.wikipedia.org/wiki/House_of_9#Cast
