House On Haunted Hill (1999): One night in the house, one million bucks, no questions asked. But there is a catch for anyone who accepts the offer. Murder is a way of life at the House On Haunted Hill, a jolting, effects-ramped remake of the 1959 cult classic that starred Vincent Price and was directed by screen horror legend William Castle. Geoffrey Rush plays twisted theme park bigshot Steven Price, who's hosting a scary birthday bash for his wife (Famke Janssen) at an abandoned institute for the criminally insane. Taye Diggs, Ali Larter, Bridgette Wilson, Peter Gallagher and Chris Kattan portray strangers mysteriously assembled for the event that could make them all very rich. Or profoundly dead. And you? We won't start the party without you.
Return To House On Haunted Hill: Sarah Wolfe was the only living survivor from the massacre at the Vanacutt Mansion, but no one believed her claims that ghosts were responsible for the gruesome murders that took place there. Now her recent and questionable suicide leaves her sister, Ariel, no choice but to devote herself to finding out who - or what - was responsible for her death. Ariel discovers that Sarah sent her the diary of the sadistic Dr. Vanacutt just before she died, offering clues to the diabolical evil that resides within the house. But the diary also makes Ariel a target in a deadly treasure hunt that leads a group of unwitting victims back to the Vanacutt Mansion, reawakening the terror imprisoned within the house on the hill. This time, the house and the evil spirits inside are out to make sure that no one leaves alive.
