Overview
Entertaining Mr Sloane is a 1970 British black comedy film directed by Douglas Hickox. The screenplay by Clive Exton is based on the 1964 play of the same title by Joe Orton. This was the second adaptation of the play, the first having been developed for British television and broadcast by ITV on 15 July 1968.
In the film, a lonely woman invites a recent acquaintance to become her lodger and her lover. Her brother likes him as well, and the new arrival plays the siblings against each other. But the lodger is eventually blackmailed into becoming both their prisoner and their shared lover, in a ménage à trois.
Plot
Murder, homosexuality, bisexuality, nymphomania, and sadism are among the themes of this black comedy focusing on a brother and sister who become involved with a young, sexy, amoral drifter with a mysterious past.
Kath is a lonely middle-aged woman living in the London suburbs with her aging father Kemp, referred to as "DaDa". When she meets Mr. Sloane sunbathing and exercising on a grave in the cemetery near her home, she invites him to become a lodger. Soon after he accepts her offer, Kath seduces him. Her closeted brother Ed makes him the chauffeur, complete with a tight leather uniform, of his pink 1959 Pontiac Parisienne convertible. Kemp recognizes Mr. Sloane as the man who killed his boss years before, and stabs him in the leg with a gardening tool.
