Better to consider the Copolla has made at least two turkeys or King Vidor if one is considering movies of the Golden Age.
I thought about adding some turkeys from directors out of Hollywood's "golden age" (e.g. Capra, Wellman, Milestone, Hawks, Ford, Cukor, Curtiz, etc.), but I realized it would be too easy. Directors involved in the studio system usually took whatever projects they were assigned, so it was inevitable that they would get some zircons among the gems.
