This 1974 horror film tells of a director and his crew filming an occult flick
in an old house where 7 family members were murdered. Soon, they become haunted by the ghoulish corpse of the murderer awoken by an ancient book. This isn't bad except for some of the editing and audio, but it still has a decent cast including horror legend, John Carradine and some eerie moments. The film seems like it inspired "The Evil Dead" and I'd
check it out at least once if you're into horror mysteries.
