I listened to a Bill Simmon's podcast with Jonathan Hock, the director of the 30 for 30 film about the legendary 1983 NC State men's basketball team, Survive and Advance. This is a nice supplement to a very good film. My write-up on the film is here.
At about the 35:00 minute mark in the podcast, they talk about the next 30 for 30 volume 2 film that Hock is working it. It is about the 1980 Soviet hockey, the team that lost to the American's in Lake Placid in the Miracle on Ice. It will air next February during the 2014 Winter Olympics in Sochi, Russia.
