A West German film production of Cat and Mouse was released in 1969, starring Lars and Peter Brandt, the sons of ex-chancellor Willy Brandt, for whom Grass tirelessly campaigned in the elections of 1965 and 1969. Directed by Hansjurgen Pohland, the film caused much outrage because of a masturbation scene, and was not notably successful. The West German/ French co-production of The Tin Drum in 1979, however, was a tremendous success. Director Volker Schlondorff stuck closely to the novel and chose the perfect Oskar in David Bennent. The film also starred Angela Winkler, Mario Adorf, and Daniel Obrychski, and, among other awards, won an Academy Award for Best Foreign Language film.
