Fox Searchlight Pictures, DNA Films and the BBC have pacted to adapt the National Theater production of Alan Bennett’s Olivier-winning “The History Boys” into a feature. Fox Searchlight president Peter Rice, DNA Films’ Andrew Macdonald and BBC Films topper David Thompson announced the project Thursday. The film will mine the same talent that won the play three Oliviers in January. Nicholas Hytner — who also serves as artistic director of London’s National Theater — will direct from a script adapted for the screen by Bennett. The storyline centers on an obstreperous class of clever, funny teenage boys and their relationships with an iconoclastic English instructor (Griffiths); a newly minted professor (Stephen Campbell Moore), retained to boost test scores; an overwhelmed history teacher (Frances de la Tour); and a headmaster (Clive Merrison) relentlessly focused on results.
