From the moment our hero Dortmunder (Robert Redford) is released from prison, that's good. But immediately he comes under attack and that's bad. Fortunately it's his Brother-in-law (George Segal) and that's good, who then offers him a job in a new crime caper and that's bad. However the man who hires them is called Dr. Amusa (Moses Gunn, superb character acting) is rich, and that's good, but he wants them to break into a top security Museum to steal an extremely valuable diamond worth millions and that's bad. However, since the doctor is willing to front all materials necessary to facilitate the theft, that's good, but once they enter the museum and get the precious stone, the thieves cannot seem to hang onto it and that's bad. Still, they are determined to retrieve the elusive gem and that's good. Throughout the movie, one cannot help rooting for the hapless thieves as their simple crime seems to take on a life of it's own and the hilarity of it all makes for a superb film which is destined to become a Classic. The cast of this film is exceptional as we have Ron Leibman playing Murch, Paul Sand as Greenberg and the incomparable Zero Mostel as Abe Greenburg. Altogether this movie is highly recommended to anyone in search of great entertainment. ****
