Saw it yesterday and enjoyed it. There have been some comments in reviews (eg the Evening Standard
) that the film takes a few liberties with the facts. On balance I think this does matter as the film is to an extent about the reality of sex rather than the sanitised, glamorous version depicted in most Hollywood films, and inventing/ignoring aspects of Mark's story shouldn't have been necessary.
Excellent acting all round and yes, there should have been more Oscar nominations.
