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 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.

Shot during the 100 days leading up to the Mr. Universe and Mr. Olympia competitions and during the competitions themselves, the filmmakers ran out of funds to finish production and it stalled for two years. Ultimately, Schwarzenegger and other bodybuilders featured in the film helped raise funds to complete production, and it was released in 1977. The film became a box office success, making Schwarzenegger a household name. The film also served to popularize the culture of bodybuilding, which was somewhat niche at the time, and helped inspire the fitness craze of the 1980s; following the film's release, there was a marked increase in the number of commercial gyms in the U.S.
