Another shaggy dog story by crime novelist Donald Westlake is smoothly adapted by William Goldman into this enjoyable caper flick, expertly directed by Peter Yates of BULLITT fame. Robert Redford heads the cast of kooky crooks -- others include George Segal, Ron Leibman and Paul Sand -- chasing after a big diamond purloined from an impoverished African nation. How they get it, lose it, and desperately try to get it back again makes for a pleasant time-waster. As usual, Zero Mostel steals the show as a sleazebag lawyer who's more crooked than the crooks. Other pluses include gritty location NYC photography by Ed Brown and a very cool score by Quincy Jones. Afghanistan-bananistan!
