THE LAST MAN ON EARTH (1964) Vincent Price is top-flight as the last man (so he thinks) on earth after a plague has turned the population into vampires. He is somehow immune and barricades himself in at night while the vampire-zombies pound outside. "Morgan, come out MORGAN!" Whoah.
HOUSE ON HAUNTED HILL (1959) Vincent Price as a millionaire who has a Halloween party! He invites people he doesn't know to spend a night in a haunted house. He awards a cash prize for anyone who can make it through. Elisha Cook Jr. as a nervous wreck is wonderful. One of director William Castle's absolute best!
