Harris Dickinson on his film 'Urchin,' navigating Hollywood and channelling John Lennon

From "Babygirl" with Nicole Kidman to Cannes Palme d'Or winner "Triangle of Sadness", Harris Dickinson is one of Britain's most compelling actors and now one of its most exciting new directors. His debut film "Urchin" is a raw and tender portrait of a homeless addict in London. As the film is released in France, he talks to Laura Di Biasio about filming the London he knows, acting versus directing, and his upcoming role as Beatles icon John Lennon.
