Frenzy is a 1972 British thriller-psychological horror film directed by Alfred Hitchcock. The second to last feature film of his extensive career, it is often considered by critics and scholars to be his last great film before his death. The screenplay by Anthony Shaffer was based on the novel Goodbye Piccadilly, Farewell Leicester Square by Arthur La Bern.
The film stars Jon Finch, Alec McCowen, and Barry Foster and features Billie Whitelaw, Anna Massey, Barbara Leigh-Hunt, Bernard Cribbins and Vivien Merchant. The original music score was composed by Ron Goodwin.
The plot centres on a serial killer in contemporary London. In a very early scene there is dialogue that mentions two actual London serial murder cases: the Christie murders in the early 1950s, and the Jack the Ripper murders in 1888.
Frenzy was the third film Hitchcock made in Britain after he moved to Hollywood in 1939. The other two were Under Capricorn in 1949 and Stage Fright in 1950. The last film he made in Britain before his move to America was Jamaica Inn in 1939.
