When game designer Milton Parker (Vincent Price) dies, all of his greedy relatives and his servants gather for the reading of his will.  Parker’s lawyer, Benstein (Robert Morley), explains that Parker is leaving behind a $200 million dollar estate to whoever can win an elaborate scavenger hunt.  Dividing into five teams, the beneficiaries head out to track down as many items as they can by five o’clock that evening.  Among the items that they have to find: a toilet, a cash register, an ostrich, a microscope, and an obese person.  Hardy har har.

The five teams are made up of a who’s who of sitcom and television actors who had time to kill in 1979.  The Odd Couple‘s Tony Randall is Henry Motely, who is Parker’s son-in-law and who works with his four children.  Soap‘s Richard Mulligan plays a blue-collar taxi driver named Marvin Dummitz (because funny names are funny) who teams up with his friend, Merle (Stephen Furst).  The Mary Tyler Moore Show‘s Cloris Leachman (an Oscar winner, no less) gets stuck with the role of Milton’s greedy sister, Mildred.  She works with her conniving lawyer (Richard Benjamin) and her stupid son (Richard Masur).  Maureen Teefy plays Milton’s niece while his nephews are played by Willie Aames and Dirk Benedict.  Cleavon Little, James Coco, Roddy McDowall, and Stephanie Faracy play the servants.

It doesn’t stop there, though.  Avery Schreiber plays a zookeeper.  Meat Loaf plays a biker who beats up Richard Benjamin.  Ruth Gordon, Stuart Pankin, Pat McCormick, and Scatman Crothers all have cameos.  Even Arnold Schwarzenegger makes an appearance as a gym instructor who knocks Tony Randall out of a second story window.

There are a lot of famous people in Scavenger Hunt.  It’s just too bad that the movie itself is barely watchable and not at all funny.  It tries to go for the zaniness of It’s A Mad, Mad, Mad, Mad World but, unless watching Willie Aames steal a clown head from Jack in the Box is your idea of hilarity, the film never comes close to succeeding.  Michael Schultz directed some classic films (like Car Wash) during the 1970s but, unfortunately, he also directed Sgt. Pepper’s Lonely Hearts Club Band and this.

Scavenger Hunt used to show up on a late night television, where it was always advertised as starring Arnold Schwarzenegger.  (He barely has five minutes of screentime.)  It was released on DVD/Blu-ray earlier this year but watching for the cameos is the only reason to take part in this Scavenger Hunt.
