he broke away sharply with his portrayal of the insane, murderous photographer Mark Lewis in Michael Powell's transgressive 1960 masterpiece "Peeping Tom."
Later in his career, he worked in four consecutive Rainer Werner Fassbinder films: "Martha," "Fox and his Friends," Effi Briest," and "Mother Kuster's Trip to Heaven." A gutsy actor!
He also worked extensively with efforts to provide relief for the people of Ethiopia, founding Humans for Humans.
