KLITSCHKO | TRAILER | BROADVIEW Pictures

Vitali and Wladimir Klitschko: two exceptional brothers, both icons, role models and heroes for many around the globe. The six-foot-six Ukrainian brothers emigrated to Germany to begin careers in heavyweight boxing in 1996, and the sport was never the same. After a 15-year reign over the ring, they made history in 2008, becoming the first brothers in the sport to hold world titles at the same time.

But who are these smart gentlemen of boxing with PhDs and fluent in four languages? Where do they come from and where are they headed? Will they really stick to the promise made to their mother, never to fight against each other? International Emmy Award winning Director Sebastian Dehnhardt followed the Klitschkos on their most personal journeys. With long forgotten archival footage, interviews of people around the world with pieces of their secrets, and time spent with them in the sacred locker room, minutes before their fights, an incredible and intimate portrait of these two boxers emerges.

The feature documentary showcases their childhoods marked by socialist drills in the midst of the Cold War, growing up on Soviet Military Bases, and the impact that the Chernobyl disaster had on their family. The film traces their path through life and finally their rise to International Boxing Super-Stardom.
