During the 1984 Los Angeles Olympics, director Bud Greenspan used 18 cameras to shoot roughly two hundred hours of footage across 21 venues. The resulting narrative adds texture and depth to some of the most stirring moments of those Games. Greenspan captures the tense, and unexpected, victory of 16-year-old Mary Lou Retton over Romania’s Ecaterina Szabo in the women’s gymnastics all-around. And he probes the epic decathlon battle between Great Britain’s Daley Thompson and West Germany’s Juergen Hingsen. His most gripping tale, however, is that of Britain’s Dave Moorcroft—the world record holder in the 5,000m at the time. A debilitating pelvic injury rules out the possibility of a medal, but he grits his teeth and finishes the race nonetheless. Just like Moorcroft, who was famed for his discipline, this classic documentary will run and run for years to come.
