Please enjoy The Damned United, a very well acted film, Colm Meaney has Britain's greatest ever manager spot on and Michael Sheen is also excellent as Brian Clough.
But remember the film is a story based on fact, not on what actually happened. Some people believe all that happened in the book and subsequently in the film to be true however most of what happens was in the authors head and is therefore largely fiction. In fact the inaccuracies and indeed the book/film have been wholly condemned by the Clough family.
An enjoyable film but factually flawed. A few examples of these factual inaccuracies include...
Leeds United did beat Derby County 2-0 in the FA Cup that year but the game was played at Elland Road NOT the Baseball Ground. Leeds however did play Derby on two other occasions that season, in the Semi-Finals of the League Cup, the first game a few weeks before the FA Cup tie so it wasn't that much of a novelty for the two sides to play each other.
Contrary to the film Leeds did not play and kick Derby off the park the game before their European Cup Semi-Final, they played them months before in that season.
Johnny Giles is not 6 foot plus and in real life Peter Taylor was a much larger man than Clough.
Brian Clough actually managed Brighton for 32 games and spent just under a year on the South Coast.
Oh and as for the very cheap shot at the end... Don Revie might have failed as England boss but at least he WAS the England boss...
To be honest there are too many more factual errors to list here, but if you take the movie for what it is, a work of fiction loosely based on fact , you can't go far wrong.
