Obscurity factor: 7
The runaway success of It's A Mad Mad Mad Mad World led Hollywood to several copycat ventures. There was a Remington Steele episode, a movie with everyone looking for something under a big "K" somewhere (that's one of those lost films that I remember from my youth but can't find - all those lost films will become a post some day) and this film from 1979. Milton Parker (Vincent Price) has died and left a huge fortune. His will decrees that it will be given in its entirety to the winning team of a scavenger hunt he has set up. The teams include his greedy sister (Cloris Leachman), her son (Richard Masur) and her lawyer (Richard Benjamin), the old man's servants (Roddy McDowell, Clevon Little, James Coco and Stephanie Faracy), his nephews (Dirk Benedict and Willie Aames), his son in law Henry Motley (Tony Randall) and his kids and a cab driver (Richard Mulligan) who helped him out once, who is eventually joined by Scatman Crothers. As the teams head out to pillage San Diego for the items on the list they wreak all sorts of havoc on population and countryside, encountering a slew of familiar faces such as Ruth Gordon, Meatloaf, Arnold Schwarzenegger in cameo roles.
Though the film has yet to be released on DVD, it can be found on VHS. It's also uploaded to YouTube in its entirety, thanks to dalekenbuck. The poster above is available from MoviePosterShop.com.
