There (in the Soviet Union) it was a science. In order to be a coach, you had to study in school.

A lot of what I know as a filmmaker is because of hockey. That's teamwork, and being able to collaborate with people, and be creative with them, and get the most out of everybody. Everyone's got different talents, and you've got to bring out the best of everybody, and use your strengths and work together, and try and evolve it rather than do what was done before you, and to push into new areas.

When I looked into the story of Soviet hockey and its players, I realized that it has nothing to do with hockey. It was a larger story using hockey as a window into the story of the rise and fall of the Soviet Union, the Russian people, with friendships and betrayals, paranoia and oppression, and the meaning of sports to people and nations around the world, and how sports was used as a political tool.

I guess the prime example is in North America there's a thing where if there's no opportunity to move forward with the puck, then a [hockey] player is told to dump the puck into the other zone. Just give up the puck and dump it in. Give it to the other team. And to the Soviet mentality in coaching, it just doesn't make any sense. If you're a skilled player, why are you going to give the puck away to the other team? Just give it away, right?

People think, sports delivers a message. It's not just about winning and losing, although that's important. It's about other things, too. It demonstrates how it can say certain things about your culture and your society.

I found a lot of stuff that's never been seen before. That was the goal: to not use cliché Cold War footage but give people a sense of the place and setting. It's a field you still need. At first it was a lot of fun, and then later it became a little bit intimidating. "Oh my God, I've got so much footage. Where am I going to put it? What am I going to do?" I ended up really only reviewing about 20 to 30 percent of what I had. So it was a task.

One ironic thing is that although (the Soviet Union) was one of the most oppressive systems, with no respect for the individual, it somehow produced the freest hockey on the planet. These guys, when they got on the ice, it was like watching jazz. They could do anything. I find that a paradox. It's interesting because I think the North American style was a lot less free. It was not encouraged to be creative.
