Trailer for Tyson: "A documentary with original interviews, archival footage and photographs shed light on the life experiences of Mike Tyson." "He was and remains the youngest man ever to win a world heavyweight title at just 20 years old. Tyson won his first 19 professional bouts by knockout, 12 in the first round. He unified the belts in the splintered heavyweight division in the late 1980s. Tyson was the undisputed heavyweight champion of the world for over two years, before losing to underdog James 'Buster' Douglas in 1990."
