He produced films by Jean-Luc Godard, Robert Bresson, Wim Wenders, Nagisa Oshima, Andrei Tarkovsky, Chris Marker, Volker Schlöndorff, Walerian Borowczyk, and Alain Resnais.
He was a principal figure in Argos Films, a company that was a very important vehicle in creating opportunities for the "Left bank" filmmakers to emerge from the overall Nouvelle Vague.
It was a niche production company with the aim of making films on art which were inspired by the work of the Italian documentary filmmaker Luciano Emmer.
In 1953, they gained an advance from a distributor that enabled them to produce Alexander Astruc's Crimson Curtain, which received a prime a la qualite.
They also produced Chronique d'un été (Chronicle of a Summer) by Jean Rouch and the sociologist Edgar Morin, a documentary which pioneered cinéma vérité.
