Overview: James Toback's film of Mike Tyson's life, told in the ex-fighter's own words, finds the controversial ex-heavyweight champion ruefully reflecting on his past, which has included a failed marriage, a conviction for rape, drugs use and fights where he didn¿t bother training, happy just to pick up the cheque at the end. But he is also forthcoming about his difficult childhood and what the loss of trainer Cus D'Amato, who was also a father figure and mentor, meant to him. Toback has know Tyson for 20 years but this is no whitewash, more a film of a troubled man unburdening himself with an honesty a stranger could never elicit.
