Leigh responded negatively to RADA's agenda, found himself being taught how to 'laugh, cry and snog' for weekly rep purposes and so became a sullen student. He later attended Camberwell School of Arts and Crafts (in 1963), the Central Saint Martin's College of Art and Design, and the London School of Film Technique in Charlotte Street. When he had arrived in London, one of the first films he had seen was Shadows, an 'improvised' film by John Cassavetes, in which a cast of unknowns was observed 'living, loving and bickering' on the streets of New York, and Leigh had "felt it might be possible to create complete plays from scratch with a group of actors." Other influences from this time included Harold Pinter's The Caretaker—"Leigh was mesmerised by the play and the (Arts Theatre) production"— Samuel Beckett, whose novels he read avidly, and the surreal writing of Flann O'Brien, whose 'tragi-comedy' Leigh found particularly appealing. Influential and important productions he saw in this period included Beckett's Endgame, Peter Brook's King Lear and in 1965 Peter Weiss's Marat/Sade, a production developed through improvisations, the actors having based their characterisations on people they had visited in a mental hospital. The visual worlds of Ronald Searle, George Grosz, Picasso, and william Hogarth exerted another kind of influence. He played small roles in several British films in the early 1960s, (West 11,Two Left Feet), and played a young deaf-mute, interrogated by Rupert Davies, in the BBC TV series Maigret. In 1964–65 he teamed up with David Halliwell, and designed and directed the first production of Little Malcolm and his Struggle Against the Eunuchs at the Unity Theatre.
