I watched it on Movietube.co its worth a watch not ground breaking tells the story of Holyfield Hopkins and Tyson.
Obviously most fans are gonna know their back stories though you hear quite a lot from Lou Di Bella who is interesting to listen too.
Catches up with all 3 and there current ventures I could listen to Tyson interviewed all day I can not think of anyone who's intensity and struggle are so evident in there voice and eyes when questioned he is a fornicating scary geezer even now.
