LIVE POLL: Best Official Winter Olympic Documentary?

Over the past 100 years, Olympic documentaries have gained a reputation as one of the more interesting subgenres in film. A distinction gained 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 Aldo Scavarda, Claude Lelouch and Masahiro Shinoda are just three examples of directors who have used their Winter Olympic opportunity to push the boundaries of filmmaking.
