Scavenger Hunt (1979, Micheal Schultz)
Here's a dud and a half. Vincent Price leaves a hunt in his will, so his awful family team up with oily lawyer Richard Benjamin. Up against them are a motley crew including Roddy McDowall ... James Coco ... Stephen Furst ... Cleavon Little ... Dirk Benedict even.
It's as flat as Norfolk though. Screeching & mugging are no substitue for writing. The Murican Rentadick.
The first misfire from 79 so far. Even Up From The Depths was funnier
