Beefcake (1999)
Beefcake (1999) is a docu-drama homage to the muscle magazines of the 1940s, '50s, and '60s—in particular, Physique Pictorial magazine, published quarterly by Bob Mizer of the Athletic Model Guild. It was inspired by a picture book by F. Valentine Hooven III (published by Taschen) and was directed by Thom Fitzgerald.
