At this festive time of year it’s hard to escape those classic double acts and their equally classic Christmas specials, think Morecambe & Wise, the Two Ronnies, French & Saunders. In this episode, Ellen E Jones and Mark Kermode explore the origins, legacy and evolution of the double act across film and TV, both in front of and behind the camera.

Guests include one half of a very famous double act, whose members have both gone on to have incredibly successful careers beyond the partnership but in very different ways. He is the Fry in Fry & Laurie, a genuine national treasure - Stephen Fry.
