Perrin began a second career as a producer with Costa-Gavras' landmark political thriller "Z" (1969), the stunning film of the aftermath of a political assassination in Greece, in which he also appeared as a journalist. (Perrin had earlier appeared in the director's first film, 1965's "The Sleeping Car Murders".) Now launched on a dual career, Perrin went on to serve as one of the producers on the Oscar-winning "Black and White in Color" (1976), the story of French and German settlers of remote African posts who decide to fight World War I on their own terrain. Perrin did not usually act in the films he produced, which include "La guerre d'Algerie" (1972), "Hors la vie" (1991) and "Microcosmos" (1995).
