With the Robert Pattinson starring film Mickey 17 fresh out in the cinema, Ellen E Jones and Mark Kermode explore the world of doppelgangers and doubles on screen.

Ellen speaks to academic and doppelganger scholar Adam Golub about the difference between clones and doppelgangers and what the doppelganger tells us about life in 2025. Ellen then talks to an actress about what its like playing a clone.

Mark speaks to director Richard Ayoade about his 2013 film The Double. It stars Jesse Eisenberg and Mia Wasikowska and is an adaptation of the classic Fyodor Dostoevsky novel from 1866. Mark and Richard discuss adapting such a classic novel, the distinct look of the film and the idea of Jung's 'shadow self' and its influence on doubles on screen.
