Frenzy is a 1972 British thriller film directed by Alfred Hitchcock. It is the penultimate feature film of his extensive career. The screenplay by Anthony Shaffer was based on the 1966 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.


Set in the early 1970s, the plot centres on a serial killer terrorizing London by raping and then strangling women with a necktie. Bob Rusk (Barry Foster), a Covent Garden wholesale produce merchant, is the murderer. However, circumstantial evidence, partially engineered by Rusk, will implicate Rusk's friend Richard Blaney (Jon Finch), who becomes a fugitive attempting to prove his innocence.
