UNDERRATED: 'Once in a Lifetime: The Extraordinary Story of the New York Cosmos' (2006):

A left-field documentary that came to DVD only last year, this film shines a light on a bizarre yet fascinating window in the '70s when international stars were wooed to play soccer in the U.S. -- with the help of Henry Kissinger, in Pelé's case -- and the sport took off for a magical instant. From your kid's league to the MLS, this is where it all began.
