Rattle of a Simple Man is a 1964 British comedy-drama film directed by Muriel Box and starring Diane Cilento, Harry H. Corbett and Michael Medwin.

Only a lively, vivid performance by Diane Cilento in a contrived role holds much interest, though a sound cast does spartan work in juggling the sparse material.

"[4] The Monthly Film Bulletin wrote: "Such merit as Charles Dyer's stage original possessed sprang from the fact that it was almost entirely a two-hander, a carefully modulated duologue between Percy and Cyrenne in which the humour almost counterbalanced the sentimentality.

Harry Corbett grossly overplays the coy gaucherie; the Italian family (including sinister, black-shirted brother, lecherous stepfather and grieving mama) is pure melodrama; and the whole atmosphere of London sin is fetchingly ludicrous.

"[7] Sky Movies called it "a rather touching and at times richly amusing extended playlet about an 'innocent' football fan from the north, and the night he spends talking to a London prostitute in her flat.
