Hello, I am looking for a movie, but I can't think of the name of it. Hopefully someone will know what I am talking about. It's where 5 people wake up in this big house and don't know where they are. The last one in there can walk out with 5 million dollars. Well they didn't realize that they had to kill each other to survive and the last one got 1 million and at the end the person walks in another room where there is 4 others with their million waiting. Hopefully I explained it OK.

Hello is it House on Haunted Hill (1999) ???

I think it's My Little Eye from 2002.

I believe it is "House of Nine" which was made in 2005. Here's the IMDB synopsis:

Nine strangers - a priest; a dancer; a designer; an aspirant rapper; a former tennis pro; a woman on probation; an unsuccessful composer and his wife; and a detective - are randomly abducted, drugged and locked in a house by a wealthy maniac. They are informed through a public address system that there are seventy-five cameras following them, and only one will survive and win US$ 5,000,000.00 to keep quiet. The psychological game begins, with fear and greed affecting the participants. Written by Claudio Carvalho, Rio de Janeiro, Brazil

Let me know, it that's it.
