During the heart of his career, from 1935 to 1960, Hitchcock made 30 feature films, so averaging more than one a year (not counting shorts, docs, and TV.) John Ford made 40 over the same period. Directors, and the industry in general, don’t crank it out like that anymore. I don’t think many keep up a film a year pace these days, but Woody’s made it part of his shtick. He and Hitch are noteable as directors whose name sells the film to the general public, but that was much rarer in Hitchcock's day.
