The people who've done well within the [Hollywood] system are the people whose instincts, whose desires [are in natural alignement with those of the producers] — who want to make the kind of movies that producers want to produce. People who don't succeed — people who've had long, bad times; like [Jean] Renoir, for example, who I think was the best director, ever — are the people who didn't want to make the kind of pictures that producers want to make. Producers didn't want to make a Renoir picture, even if it was a success.
