Faithful (1996)

Synopsis
A hit man discovers the pros and cons of getting to know his victim in this dark comedy. Margaret (Cher) is supposed to be celebrating her 20th wedding anniversary, but she hardly feels like having a party; her marriage is in sad shape, her husband Jack (Ryan O'Neal) has just called to say he's going to be working late (she realizes this means that he's actually with his mistress), and she's sunk into a deep depression that borders on the suicidal. After a long bath, Margaret discovers that she's not alone in the house; Tony (Chazz Palminteri), a hit man, has been hired by Jack to knock her off (Margaret's death would mean a $5 million insurance claim for Jack), and he ties her to a chair, waiting for a call from Jack that signals he's out of town and that it's all right to proceed with the execution. With nothing to do while they wait, Tony and Margaret begin to talk; Margaret starts to feel like death isn't such a good idea after all, while Tony isn't so sure he wants to kill her anymore. Faithful was based on a stage play by co-star Palminteri; Robert DeNiro, who made his directorial debut with A Bronx Tale, written by Palminteri, served as co-producer for this film. ~ Mark Deming, All Movie Guide
