Pumping Iron

Pumping Iron is a 1977 American docudrama about the world of professional bodybuilding, with a focus on the 1975 IFBB Mr. Universe and 1975 Mr. Olympia competitions. Directed by George Butler and Robert Fiore and edited by Geof Bartz and Larry Silk, it is inspired by the 1974 book of the same name by photographer Butler and writer/paintball creator Charles Gaines and nominally centers on the competition between Arnold Schwarzenegger and one of his primary competitors for the title of Mr. Olympia, Lou Ferrigno. The film also features segments on bodybuilders Franco Columbu and Mike Katz, in addition to appearances by Ken Waller, Ed Corney, Serge Nubret, and other famous bodybuilders of the era.
