No sooner was John Dortmunder (Robert Redford) released from prison than his brother-in-law Andy Kelp (George Segal) recruited him to a diamond heist. Dr. Amusa (Moses Gunn) was a UN Representative from an African country that laid claim to the Sahara Diamond. Several other countries also made claims. In order to strengthen his claim, Amusa wanted the diamond acquired; it was on display in the Brooklyn Museum. He offered $25,000 each to a four-man team. He further acceded to pay expenses and a weekly stipend. The two added men were Murch (Ron Leibman), who could operate any vehicle, and Allan Greenberg (Paul Sand), an explosives expert. The plan went reasonably well, except that one of them got caught with the diamond. A new plan must be developed to break him out of jail. But they still don't have the diamond!
The movie is a comedy of errors that sees the heroes always one step away from securing the diamond and each new plan requires ever increasing expenses, much to Amusa's irritation. Zero Mostel appears as a shady lawyer who proves to be yet another hurdle to overcome.
Great popcorn fun and highly recommended.
