I’m glad that a William Castle-directed horror film made it onto the Internet Archive Top 100. In the House on Haunted Hill, Vincent Price plays an eccentric millionaire who pays strangers to stay overnight in a haunted house. As the night progresses, the guests are trapped inside the house with ghosts, murderers, and other terrors.
In some theaters that showed the film, Castle set up an elaborate pulley system which allowed a plastic skeleton to be flown over the audience at the appropriate time. We don’t have that here, but Castle and Price make a great combination.
