Green Grow the Rushes is a 1951 British comedy film directed by Derek N. Twist and starring Roger Livesey, Richard Burton and Honor Blackman. It was the first film to be released by ACT Films, an entity formed by a trade union for filmmakers. The film was produced by John Gossage and funded by the National Film Finance Corporation and the Co-Operative Wholesale Society Bank. It is an adaptation of the 1949 novel of the same title by Howard Clewes.

Roger Livesey was a British stage and film actor. He is most often remembered for the three Powell & Pressburger films in which he starred: The Life and Death of Colonel Blimp, I Know Where I'm Going! and A Matter of Life and Death. Tall and broad with a mop of chestnut hair, Livesey used his highly distinctive husky voice, gentle manner and athletic physique to create many notable roles in his theatre and film work.
