With films like "The Last House on the Left" and "The House that Dripped Blood," 1974's "The House that Vanished" hit America's Drive-In theaters in the 1970s. A bygone era we all miss. Mystery mixing with horror, a beautiful damsel in much distress, and creepy suspects aplenty grace this film. Andrea Allan stars as a fashion/underwear model who likes to get undressed. You might remember Ms. Allan as one of the purple-haired control room gals from the show "U.F.O."
