Christopher Nolan on Oppenheimer, what is Cynghanedd?, club culture under threat

Presenter Nick Ahad meets Christopher Nolan, director of the much anticipated Oppenheimer film. It tells the story of the American physicist J. Robert Oppenheimer who, in 1943, assembled a group of scientists in Los Alamos to create the world’s first atomic bomb. Ahead of the National Eisteddfod, the annual festival of Welsh poetry and music, we learn about the poetic tradition of Cynghanedd from Dr Mererid Hopwood and Ceri Wyn Jones. And as nightclubs continue to close across Britain, we look at club culture and why people need to dance together. Nick is joined by the music journalist John Harris and Emma Warren, author of Dance Your Way Home.Presenter: Nick Ahad Producer: Simon Coe
