House of 9 is a 2004 psychological horror film directed by Steven R. Monroe and starring Dennis Hopper and Kelly Brook.

The film is presented with "live feeds" from hidden surveillance cameras, showing the nine people turning from cooperative escape attempts to a killing fest.

The players attempt to escape by breaking down the door using a dining table as a battering ram and digging through the basement, but to no avail.

In the dining room, the players introduce themselves: Father Duffy is a priest, Jay is a cop with a pistol, Lea is a dancer, Claire is a tennis player, Francis is a musician and Cynthia is his wife, Al B is an ambitious rapper, Shona is a drug addict, and Max is a fashion designer.

When Cynthia intervenes, Al B pushes her and she falls back knocking her head against a steel railing, killing her.

Meanwhile, Francis visits Lea in her room in her bathroom, ripping the light fixture from the wall and throwing it into the sink, electrocuting her.

Father Duffy is still in Lea's room when Francis comes in not expecting him to be there and pretends he was looking for him because it was dinner time, he starts feigning shock of seeing Lea's body trying to insinuate that she must have committed suicide "That she was Weak" claiming it will be more food given now because of her death, which Father Duffy doesn't believe & accuses him of doing it for the money promised.

Francis then starts screaming "I Won, Gimme My Cash" over & over to the person perceived to be behind the cameras watching when he hears the sound of Lea who is trying to put the tank lid back on the toilet but accidentally breaks it alerting him.

She plays the tape and sees the camera footage of the foyer with the remaining bodies having been removed and the house cleaned up.

Lea stares at the screen in shock as The Watcher says, "Happy viewing..." Filming for House of 9 took place in Romania.

"[4] DVD Talk said, "See it for the hotties, for the nasty kill scenes, and for the always-insane Dennis Hopper at his most adorably weird.

"[5] The Hartford Courant reviewed the film, noting that "As with "Saw II'' (and almost any slasher movie these days), the killings become tedious, something to be endured so you can see how it ends.
