Herakles (1962)

Basically, 'Herakles' is an omnium-gatherum of film clips depicting images of machismo. Some of those images are explicitly macho: we see various body-builders flexing their biceps and triceps. Other images seen here are not macho in the literal sense, but are indirectly related to testosterone or cojones on some level: we see military aircraft making bombing raids, and footage of car crashes.
