The poet and the film-maker collaborated on the BAFTA Cymru award-winning Aberfan: The Green Hollow, an hour-long film poem about the 1966 tragedy, and are now working on To Provide for All People – a new film celebrating the 70th anniversary of the founding of the NHS. They discuss the stories and people who feature in the new film, and the freedoms and forms of working with poetry. They preview clips of the NHS film that will be broadcast later in the summer.
