Fan Casting A Fish Called Wanda

In London, four very different people team up to commit armed robbery, then try to doublecross each other for the loot. Wanda brings her new secret lover, Otto to England to help her and her lover George and stuttering animal lover Ken steal $20 million in diamonds. Wanda and Otto then turn in George to the police so they can have the loot for themselves, but George has already moved the diamonds and only he knows where they are. All four of the criminals start double-crossing each other to try to get to the diamonds before anyone else. Wanda tries to find them by "getting close" to George's barrister, Archie Leach, because if George pleads guilty he will tell Archie where the diamonds are to cut his sentence. Absolute hilarity ensues.
