An unruly bunch of bright, funny sixth-form boys in pursuit of sex, sport and a place at university. A maverick English teacher at odds with the young and shrewd supply teacher. A headmaster obsessed with results; a history teacher who thinks he's a fool. In Alan Bennett's screenplay, staff room rivalry and the anarchy of adolescence provoke insistent questions about history and how you teach it; about education and its purpose. Fox Searchlight Pictures, DNA and the BBC have joined forces to bring the National Theatre's award-winning production of ''The History Boys'' to the big screen, directed by Nicholas Hytner from a script adapted for the screen by Alan Bennett.
