Haven't seen the film but read the book. Both have been panned by his family and Johny Giles successully sued for how he was portrayed in the book. It is fiction and like everyone else who was around to witness events, he complained that the story told is basically not true and damages reputations.
Giles also made the point that the dead can't see and he was appalled how Clough was portrayed.
Randy, if you want to see how bad Leeds could be, just watch the Chelsea v Leeds FA cup replay from 1970 - not that Chelsea were shrinking violets. The game would have had to be abandoned if played now.
"The replay at Old Trafford, watched by a television audience of 28 million, a record for an FA Cup final, became one of the most notorious matches in English football. Modern day referee David Elleray "replayed" the match years later, and concluded that the sides should have received six red cards and twenty yellow cards between them. Not long into the match, Ron Harris caught Eddie Gray with a kick to the back of the knee, an action which virtually immobilised the Scot. Charlton kneed and headbutted Peter Osgood and Chelsea's goalkeeper Peter Bonetti was injured after being bundled into the net by Leeds' Jones, who minutes later rounded the limping immobile Bonetti and scored the opener. Norman Hunter and Ian Hutchinson traded punches while McCreadie and Johnny Giles lunged at opposition players.
Chelsea's equaliser eventually came after a flowing move from which Osgood scored with a diving header from a Charlie Cooke cross. Charlton should have been marking Osgood, but had 'lost' him, whilst chasing Hutchinson to exact retribution for a deadleg administered in the Chelsea penalty area a minute or so earlier. In scoring, Osgood became the last player to date to have scored in every round of the FA Cup. With the game at 1–1 in extra time, Hutchinson sent in a long throw-in which missed almost every player in the penalty area, but came off Charlton's head and looped towards the far post, before being put into the unguarded net by Webb to give the Londoners the lead for the first time. Chelsea kept the lead to secure their first FA Cup win".
Ah, the good old days!
