However, I do remember this from vaguely 1975 and it was crystallized by the documentary #WhenWeWereKings which also has contributions from Mailer and others like #GeorgePlympton and goes into the build up to the fight which took place in #Zaire under #Mobutu.
The book is amazingly written and the way Mailer describes events is superb in my opinion. He really brings the training and the sparring (both literal and figurative between Ali and Foreman) to life. [Cont...]
The reason I got it is because of the documentary, which I found very interesting.
An interesting device the author uses is always to refer to himself in the third person as Norman or Mailer, though not through arrogance but as a form of stepping back from himself as he took part in the events, through interviews and so on and so he tries to be as dispassionate as possible about that aspect. It did take a bit of getting used to but you soon forget about it.
