From an impoverished neighbourhood in South London, Charlie Chaplin became one of the most significant figures in the development of cinema. More recently, TV writers like Sophie Willan and Michaela Coel have transformed the way working class lives are depicted on TV, from the concerned paternalism of the 1960s to a more celebratory view from the inside in the 2020s. In this week's edition of Radio 4's arts and ideas discussion programme, Matthew Sweet charts these changes, and considers what they mean for our understanding of class categories in wider society. With TV historian Laura Minor, art historian Jacqueline Riding, novelist Adelle Stripe, and historian Samuel Johnson-Schlee. Plus, an interview with Ian La Frenais, co-creator of such comedy classics as The Likely Lads and Porridge.
