Sweet Revenge is a 1998 British black comedy film written and directed by Malcolm Mowbray, adapted from Alan Ayckbourn's play The Revenger's Comedies. The film follows Henry Bell and Karen Knightly, two disillusioned characters who, after meeting on a bridge where both are contemplating suicide, form a pact to carry out revenge on each other’s behalf. This sets off a series of absurd and farcical events, with dark humor highlighting the futility and ridiculousness of their revenge schemes. The film satirizes human behavior, blending Ayckbourn's sharp wit with Mowbray’s comedic direction.

The film had a brief and modestly successful theatrical run in Italy under the title Amori e vendette (Loves and Vendettas) but failed to find a distributor elsewhere. It eventually was telecast in the UK by BBC Two on 30 December 1999, under the title The Revengers' Comedies. It was released on videotape in the United States and France and on DVD in the US.
