Leigh was born to Phyllis Pauline (née Cousin) and Alfred Abraham Leigh, a Doctor. Leigh was born at Brocket Hall, Hertfordshire, because his mother, in her confinement, went to stay with her parents for comfort and support while her husband was serving as a captain in the Royal Army Medical Corps. Leigh was brought up in Broughton, Salford. He is from a Jewish immigrant family whose surname, originally Lieberman, had been anglicised in 1939 "for obvious reasons". When the war ended Leigh's father began his career as a general practitioner in Higher Broughton, "the epicentre of Leigh's youngest years and the area memorialised in Hard Labour." Leigh went to Salford Grammar School, as did the Director Les Blair, his friend, who produced Leigh's first feature film Bleak Moments in 1971. There was a strong tradition of drama in the all-boys school, and an English master, called Mr Nutter, supplied the library with newly published plays. Outside of school, Leigh thrived in the Manchester branch of Habonim. He attended summer camps and winter activities over the Christmas break all round the country in the late 1950s. Throughout this time, (and though supplemented by his discovery of Picasso, Surrealism, The Goon Show, and even family visits to the Hallé Orchestra and the D'Oyly Carte), the most important part of his artistic consumption was the cinema. In 1960, 'to his utter astonishment', he won a scholarship to RADA. Initially trained as an actor at RADA, Leigh went on to start honing his directing skills at East 15 Acting School where he met the Actress Alison Steadman.
