Indecent Proposal (1993)

One of the biggest teases in film history, this film's sensational plot finds a young wife (Demi Moore) solicited for sex by a wealthy bachelor (Robert Redford), for which the latter offers to pay a cool million bucks to her and her underachieving husband (Woody Harrelson). The two accept Redford's deal, and their marriage is ruined. The twist in the film, though, is that the sin doesn't lie with the rich guy, but rather with this unfocused, immature, equivocating couple who would do such a thing, naively believing it would get their lives on track. Director Adrian Lyne, who caused an even greater stir by filming Lolita (the one starring Jeremy Irons), thus pulls a kind of thinking person's bait and switch, promising something tawdry and then turning the story around so its focus is on a rite of passage for the estranged spouses.
