The latest film which has provided me multiple joyful viewings is The History Boys. Wonderful script by Alan Bennett from his incredibly witty Tony and Olivier award winning play, directed by Nicholas Hytner [Madness of King George (also from an Alan Bennet play), The Crucible. The Object of My Affection - but, more than a film director he is one of Britain's greatest theater and opera directors]
-- with an unbelievable cohesive ensemble cast of eight wonderful young British actors, Richard Griffiths [who was in the recent controversial London production of Equus with that Harry Potter actor dropping his kit - come to think of it Richard Griffiths was also in a Harry Potter film !] and the subtley stunning Frances de la Tour. Makes me upset that I did not make more of an effort to see the original National Theatre production in London or the tour to New York last year.
If you watch the film and enjoy it, make an effort to get a hold of the original play-script [not just the film script]
and read the rest of the play, as about 3/4 of an hour of material had to be excised in the film adaption.
