There’s only one talking head punctuating clips in this film. It has a Maori warrior-like tattoo on its left side and the words coming from the mouth are measured and softly spoken. It is, of course, Mike Tyson, giving thoughtful and honest comment on his rise to, tenure as, and fall from heavyweight champion of the world. Toback does a grand job of mining archives for news and fight footage. Seeing Tyson in action can still raise a gasp, thanks to his unsurpassed power, speed and skill. Toback had been friends with Iron Mike for 20 years when they made this, so he can ask about Tyson’s rape conviction or “colourful” ex-manager Don King.
