A dying man wants proof of the existence of the afterlife, so he hires a physicist to assemble a team to go investigate the world's "most haunted" house; the Belasco House. The physicist, his wife, and two spiritual mediums (one the sole survivor from the last team to attempt an investigation there) enter the house, and fight to survive. Richard Matheson (author I Am Legend) wrote the story, and Roddy McDowall stole the show. Anybody else remember this Hammer-esque house of horrors? I liked it, despite its occasionally over-the-top moments.
