-->-- The movie's {{Tagline}}

''Indecent Proposal'' is a 1993 drama film directed by Adrian Lyne (''Film/FatalAttraction'', ''Film/{{Flashdance}}'') and starring Creator/DemiMoore, Creator/RobertRedford, and Creator/WoodyHarrelson.

David and Diana Murphy (Harrelson and Moore) are a happy yuppie couple of childhood sweethearts involved in the real estate industry who run into financial trouble when the said industry undergoes downturn. They embark on a trip to Las Vegas to try and win it big, but lose everything. Just when all hope seems lost, the two encounter billionaire John Gage (Redford). Gage is attracted to Diana and thus offers the couple a proposition; he will give them one million dollars if he can spend one night with her. After much terse debate, they decide to accept, assuming it will be just sex and that they'll be able to forget about it. However, after the deed is done it turns out it isn't that easy to just pass up...

!!This film provides examples of:
* AdaptationDyeJob: Diana's character is blond in the book.
* AsHimself: Creator/BillyConnolly, celebrity auctioneer.
* AvoidTheDreadedGRating: There is exactly one use of the word "fuck" in the film. As the only onscreen sex is not actually explicit, this was presumably put in there to bump up the rating.
* BettyAndVeronica: A GenderFlipped example: Diana (Archie), her husband David (Betty), and billionaire John (Veronica).
* BreakHisHeartToSaveHim[=/=]IWantMyBelovedToBeHappy: Realizing that Diana misses David and will never be truly happy with him, Gage lies to her and tells her that she was just one of many "million dollar girls". She realizes that he's doing this to make it easy for her to leave but doesn't let on.
* DoubleStandard: Gage's continued pursuit of Diana following their night together (something that was ''contractually agreed on'' to be one night and no more)--showing up at her job uninvited and unannounced, manipulating situations to bring them together--is presented as adorable and playful, despite the fact that she's clearly not interested and finds his behavior upsetting. When she gets fed up and shows up at ''his'' workplace uninvited and unannounced to tell him off and demand that he leave her alone, ''her'' behavior is presented as alarming and disruptive even though she has every right to be angry with him. So a woman acting like a crazy stalker is...a crazy stalker. A man acting like a crazy stalker is in love.
* {{Cuckold}}: A couple desperate for money agree for the wife to have sex with a billionaire, and the experience tears the two of them apart. She winds up temporarily living, and having a sexual relationship with, the billionaire, and he is portrayed as an overall better man than her husband in most ways.
* {{Fanservice}}: Demi Moore at her most beautiful.
* HappilyMarried: Prior to meeting Gage, David and Diana are shown to be deeply in love with each other. In the end, Gage lets Diana go because he realizes that she'll never love him as much as she loves David.
* HeroicBSOD[=/=]MyGodWhatHaveIDone: David starts to experience both tropes shortly after leaving Diana in Gage's hotel room. They kick in full-force when he's too late to stop her from leaving with him.
* HollywoodDateless: Are we really supposed to believe that a man as good-looking and wealthy as John Gage needs to pay women a million dollars to go to bed with him?
* LadykillerInLove: It's implied that Gage was quite the womanizer, but falls for Diana precisely ''because'' she isn't impressed by his wealth--indeed, she's quite offended by his "money for sex" offer and blasts him for thinking that she or her affection is something that he can buy.
* MakingLoveInAllTheWrongPlaces: Early in the film, David and Diana make love on the floor of their kitchen.
* ManOfWealthAndTaste: Gage.
* MayDecemberRomance: Robert Redford is 26 years Demi Moore's senior.
* MillionairePlayboy: Gage, again, though it's "billionaire, rather..
* {{Money Fetish}}: Diana rolls around in the couple's casino winnings on their hotel bed. David soon joins her for a lovemaking session.
* MovingTheGoalposts: When Diana finds out that Gage has bought their property, she offers him $1 million dollars for it. He tells her, "the price is two". She quickly cottons onto his game and snaps, "And if I had two million, the price would be ''four'' million."
* NotIfTheyEnjoyedItRationalization: David accuses Diana of being attracted to Gage and having agreed to the deal because she wanted to sleep with him in the first place. She denies it, claiming to be very upset about everything, but after some more browbeating by David, admits that the sex was good.
* QuestionableConsent: Diana and David only even consider the offer from Gage because they're broke. By the time she goes to Gage's yacht, it's only after a contract has been hammered out. Gage ups the ante by flipping a coin and telling her that if she wins, he'll void the deal. He wins and...cue SexyDiscretionShot. At the end, it's revealed that Gage's coin is double-sided. So aside from the fact that she would never have even considered sleeping with him in the first place were it not for the money, both the contract and the coin toss leave her feeling obligated to do this.
* RaceForYourLove: David races back to Gage's penthouse to stop the liaison from happening, but he's too late as she's already been whisked away to his yacht.
* RaceLift: Gage's character in the novel is Arabic. Also, David's name in the novel is Joshua, and he's Jewish.
* RejectionAffection: Gage continues pursuing Diana even though she clearly finds his behavior upsetting, even flat-out telling him "I hate you" at one point. He completely dismisses this much as he's dismissed all her other rejections, telling her, "You ''wish'' you hated me." and trying to kiss her even as she's pulling away.
* RichSuitorPoorSuitor: Gage and David, respectively.
* ScarpiaUltimatum: The basis of the plot.
* WealthyYachtOwner: Gabe whisks Diana off to one of these.
