On Any Sunday follows the lives of motorcycle racers and motorcycle enthusiasts. The 1971 documentary looks at the people whose lives are devoted, and sometimes risked, in the pursuit of racing. The film is narrated and co-produced by actor Steve McQueen, an avid racer, whose racing is included in the film. The documentary required shooting over 150 hours of footage over a two-year period. It has become known as the new standard of motorcycle films. The film features racing and racing styles from around the world. In northern Canada, motocross racers use two-inch steel spikes as traction on the ice. Other races come from the Mojave Desert and Europe. But the film focuses primarily on American racing and reveals the day-to-day lives of racers on and off the track. On Any Sunday shows the variation and physical demands of motorcycle racing as well as the passion that lives within those who participate.
