 With wit and athletic genius, with defiant rage and inner grace, Muhammad Ali forever changed the American landscape. Fighting all comers, Ali took on the law, conventions, the status quo and the war-as well as the fists in front of him. Ali both ignited and mirrored the conflicts of his time and ours to become one of the most admired fighters in the world. Forget, now, what you thought you knew. Behind Ali's seismic accomplishments, superstar Will Smith and Academy Award?- nominated director/writer Michael Mann will take you into the heart and life of the boxer, the legend and, more importantly, the man. He talked and danced. He fought and struggled. Ali shook the world.
