NT @50: Alan Bennett and Frances de la Tour platform

As part of the celebrations for the country's leading theatre's birthday, there will be a series of platforms called National Histories where some of the NT's leading artists tell their personal stories about the theatre. This one sees playwright Alan Bennett - 'The History Boys' and 'The Habit of Art' and actress Frances de la Tour - who starred in Bennett's 'The History Boys' and 'People' - talk and answer questions.
