Alma Lucy Reville, Lady Hitchcock (14 August 1899 – 6 July 1982) was an English screenwriter and film editor.

[5] Twickenham Film Studio, where Reville first worked, closed in 1919, but she was given a job at Paramount's Famous Players–Lasky, a subsidiary of the American company based in Islington, where she met her future husband, Alfred Hitchcock.

[7] In 1928, when they learned that she was pregnant, the Hitchcocks purchased "Winter's Grace", a Tudor farmhouse set in 11 acres (4.45 ha) on Stroud Lane, Shamley Green, Surrey, for £2,500.

Reville focused primarily on preparing and adapting her husband's scripts, including those for Rebecca, Foreign Correspondent (both 1940), Suspicion (1941) and Saboteur (1942).

[12] Reville had a keen ear for dialogue and an editor's sharp eye for scrutinising a film's final version for continuity flaws so minor they had escaped the notice of the director or the crew.

It was Reville who noticed Janet Leigh inadvertently swallowing after her character's fatal encounter in Psycho (1960), necessitating an alteration to the negative.

"[13] When Hitchcock accepted the AFI Life Achievement Award in 1979, he said he wanted to mention "four people who have given me the most affection, appreciation and encouragement, and constant collaboration.

The first of the four is a film editor, the second is a scriptwriter, the third is the mother of my daughter, Pat, and the fourth is as fine a cook as ever performed miracles in a domestic kitchen.
