You have to hand it to NBCUniversal; they know how to maximize cross-promotional opportunities. What better way to promote a film about an Olympic athlete taken as a prisoner of war during World War II than to put a teaser trailer for it right smack dab in the middle of the Olympics themselves and get Tom Brokaw to narrate it as if it were some sort of journalistic piece? That's exactly what they've done with Unbroken, a film about former Olympian Louis Zamperini.
