Levy directed one film, Lord Camber's Ladies (1932), which was the only film produced by Hitchcock which he did not himself direct.
Levy was first elected at the 1945 general election, for the Eton and Slough constituency, and stood down at the 1950 general election. Politically, Levy was on the left of the Labour Party and became an active member of the Campaign for Nuclear Disarmament). As a sympathiser with the Zionist movement, he also opposed Foreign Secretary Ernest Bevin over Bevin's policies towards Palestine and Israel.
As an MP, Levy made an unsuccessful effort to abolish theatrical censorship in Britain, and towards the end of his life, he was the principal author of a report opposing the arguments for censorship made by Lord Longford, the anti-pornography campaigner. He was married for more than 40 years to the American-born screen and stage actress Constance Cummings; they had one daughter and one son.
