NT @50: Kenneth Cranham and Lesley Manville 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 actors Kenneth Cranham - 'The UN Inspector' and 'An Inspector Calls' and Lesley Manville - 'Grief' and 'His Dark Materials' - talk and answer questions.
