“Price plays an eccentric millionaire who, lacking friends, finds a sure-fire way to fill his supposedly haunted house for a party. He invites five strangers to spend the night--the entire night--with the promise of paying them $10,000 for their company. One of the guests, however, turns out to be not a stranger, but Price's wife's lover: the unhappy spouse has her own ideas about how to throw a wild party. This sinister, campy shocker goes for broke in the fright department (headless apparitions, ambulatory skeletons, blood-dripping ceilings) all the elements audiences of the fifties and sixties expected and received in abundance. Said Variety: ‘In the wealth of grim and grisly pictures that make up the bulk of exploitation fare these days, there are few genuine ghost stories....House on Haunted Hill is expertly put together...” American Film Institute
