The Fiendish Plot of Dr. Fu Manchu is a 1980 comedy film, primarily notable as the final film of Peter Sellers, David Tomlinson and John Le Mesurier. Pre-production began with Richard Quine as director. By the time the film entered production, Piers Haggard had replaced him. Peter Sellers handled the re-shoots himself. Based on characters created by Sax Rohmer, the film stars Sellers in the dual role of Fu Manchu, a stereotypical Chinese evil genius, and English country gentleman detective Nayland Smith. Released only two weeks after Sellers death, the film was a commercial and critical failure. It was also the final screen appearance for Tomlinson, who retired from acting shortly before its release.
