Over the past 100 years, Olympic documentaries have gained a reputation as one of the more interesting subgenres in film. A distinction earned by being important chroniclers of sports history, by telling compelling stories and by attracting master directors. These films aim to capture the soul of the games, while also considering them in a broader social and cultural context. Directors Leni Riefenstahl and Kon Ichikawa are just two examples of directors who have used their Olympic opportunity to push the boundaries of filmmaking.
