Entertainment lawyer Walter Fielding (Hanks) and his violist girlfriend Anna (Long) are swindled into buying an old house that's falling apart at the seams. As they keep getting further in debt in their efforts to restore the house, the pressure starts taking a toll on the couple. Part of Hanks's early period of comedies made before Philadelphia, the film is also one of the reasons Shelley Long quit the cast of Cheers hoping to make a transition to movies.
The Money Pit provides examples of:
- The Ace: Max. He is better-looking than Walter, is richer, his life has not fallen to pieces (other than losing Anna) and has a nice job as a famous orchestra conductor.
- The Alleged House: Buying, living in, and attempting to repair one of these is central to the plot.
- Analogy Backfire: Walter defends buying the dubiously low-priced mansion by calling it an overlooked bargain and likening it to that short line at the DMV that hardly anyone gets into. Anna notes that she actually did get into that line once, and discovered it was for farm vehicles only.
- Argentina Is Nazi-Land: Used as part of the swindle's hook: Estelle explains to Walter and Anna that her husband Carlos (who is German but they met in Paraguay) got in legal trouble with Israeli Intelligence because he used to be Hitler's pool boy, so now the house needs to be sold (cheap and quick) because of his deportation.
- Bait-and-Switch: The letter from Walter's dad at the beginning of the movie has him ask Walter to "say hi to the Cheap Girls for him", which considering that he went to Brazil to dodge a major scam charge implies that he's mocking his victims... only to turn out that one of Walter's clients is a rock group called "the Cheap Girls".
- "Begone" Bribe: To avoid some regulations. At one point it is more of a "please come" bribe, because the Jerkass permit guy just won't arrive unless Walter offers him some money.
- Big Fancy House: Eventually, anyway. The whole movie revolves around its renovation.
- Bookends: Fielding's dad appears at the beginning of the film to help establish how screwed Walter is (his dad was a powerful attorney until he ran away with the money of several clients) and appears at the end as yet another victim of the fraudulent real estate salesmen that sold Walter his lemon.
- Burger Fool: Walter catches a ride home with a pizza delivery guy dressed as a stereotypical Italian chef, driving a ludicrous Volkswagen Beetle completely covered in flashing lights and blaring a silly song about pizza (which was not created for the movie, but is in fact a real tune by children's musician Peter Alsop) from external speakers.
- Bunny-Ears Lawyer: The Shirks are very sleazy and their work crew looks like it belongs on a Mad Max film, but they deliver. The really hard part for Walter is getting the money and the permits.
- Chekhov's Gunman: Estelle appears at the beginning and ending of the film scamming people with lemon homes. Her husband Carlos doesn't shows up when she's conning Walter but his appearance at the end shows that he's definitely German (or can pass for one convincingly enough for the "in trouble with Israeli Intelligence" part of the earlier swindle).
- Con Man: Estelle and Carlos (the husband/wife team who stick Walter and Anna with the titular fixer-upper).
- Drama Queen: Both Anna and Walter, when driven to a breaking point. Leads to a big zig-zag between Ham-to-Ham Combat and Snark-to-Snark Combat in this sequence.
- Hair-Trigger Temper: The permit guy. What little we see of him suggests that he's a gigantic asshole.
- Head-Turning Beauty: When Anna and Walter are having their big argument (see Drama Queen, above), she's wearing a very form-fitting red dress. The construction workers keep ogling her or trying to proposition!
- I Lied: It's only after Anna's on the verge of breaking up with Walter for good that Max comes clean about what happened the night she spent at his loft. To that point, he'd been letting her think they'd slept together in a ploy to get back with her:"You slept in the bed, and I took the sofa. Sex would have been a miracle."
- Jerkass: Max again.
- Really, every contractor Walter and Anna employ is either a crook, aggressively unlikeable, or both.
- Karma Houdini: The con artists who sold Walter and Anna the titular money pit get away completely scot-free free and continue selling lemons to unsuspecting sucker.
- Karma Houdini Warranty: As the movie begins, Walters father is living the high life in Rio de Janeiro, marrying a beautiful woman young enough to be his daughter, after stealing millions of dollars from his clients and leaving his son holding the bag for everything. Come the last scene in the film he and his new wife are buying a gorgeous mansion in South America — from the same two con artists who sold Walter and Anna their lemon.
- Laughing Mad: Walter tends to do this a lot when under stress.
- Lonely Rich Kid:Fielding: Benny, if you don't loan me that money, I'll...
Benny: You'll what, huh? You'll what?
Fielding: ...I'll not like you anymore.
Benny: [sad tone] ...All right.
- My God, What Have I Done?: Immediately following their vicious, end-of-the-relationship fight over her cheating with Max (that she's unknowingly innocent of), Anna slams the door, then drops her belligerent facade and bursts into horrified Tears of Remorse.
- Pet the Dog:
- Max convinces Walter to make up with Anna by reminding him that, being a more decent man than he, losing her would affect Walter far more than it would a guy like Max. Of course, this only comes after Max sharply Kicked The Dog by tricking Anna into thinking she'd cheated on Walter, in hopes of splitting them up. Max also graciously conducts his orchestra at Walter and Anna's wedding.
- When the job is finally done, project foreman Curly also leaves Walter and Anna with a bit of parting advice about how despite everything that had gone wrong with it, the house proved to be fixable because it had a good, strong foundation. Both understood exactly what he was getting at, and they decide to patch up their relationship on the spot.
- Rewatch Bonus: Notice how carefully Estelle avoids all the pratfalls and hazards of the house we're soon to see when giving Anna and Walter the tour.
- Rich Suitor, Poor Suitor: Anna has Max and Walter.
- Rock Me, Amadeus!: The music for the wedding at the end is provided by Max and his orchestra and one of the rock bands Walter represents. The wedding scene, as a result, is an orchestral/rock arrangement of "Ode To Joy".
- Running Gag:
- "They testing missiles here, or what?" Said by almost everybody who sees the gigantic crater the repairs did, even pizza deliverymen and Vietnamese chafeurs.
- The Shirks and their work crew keep telling anybody who asks how long the repairs are gonna take that it's going to be finished in two weeks, even after they have been at it for months and it just doesn't looks like they will ever end it.
- Shady Real Estate Agent: He even celebrates with his staff when Fielding decides to buy the house.
- Shockingly Expensive Bill: Subverted in the asking price of the house; played straight when they have to pay to repair it.
- Sins of Our Fathers: Hoping to clean the family name, Fielding tries constantly to make up for the money his dad embezzled.
- Snark-to-Snark Combat: Between Anna and Walter:
- Spoiled Brat: Benny.
- Those Wacky Nazis: Carlos, or that's his excuse(!).
- The Unfair Sex: Played with. While it is revealed Anna didn't actually cheat with Walter, she is unaware at first and convinced out of principle that Walter should forgive her. As she puts herself "He can't forgive me, so I can't forgive him." In the end Walter is convinced to make up with her and a happy ending ensues. The only reason Anna believes Walter should forgive her for sleeping with Max is because Walter spent an entire evening, from sitting down to dinner 'til after going to bed, nagging her over whether anything happened between her and Max, constantly promising that if anything did happen he would be perfectly okay with it, and not blame her or hold her responsible. Anna actually believes him, which is why she expects him to forgive her and sees his subsequent reaction and behavior as him being a hypocrite, which is why she can't forgive him. Still, it's hard to believe Walter would be owed forgiveness on this somewhat spurious liability if the roles were reversed.
- What Did I Do Last Night?: Anna wakes up in Max's bed in the third act after a bender and Max tells her that they had sex. In reality he slept in the couch and let her have the bed, and he lied because he's still a bit of a Crazy Jealous Guy at the moment (he confesses once he sees that this has almost demolished Anna's and Walter's relationship shortly after).
- White-Collar Crime: The reason Fielding's father is abroad. He stole two and a half million dollars from his firm's clients and left Walter with the bill.
- Whole Plot Reference: Suspiciously similar to the 1948 classic Mr. Blandings Builds His Dream House.
- Wholesome Crossdresser: One of Walter's clients is a rock band that's taken to wearing dresses as their newest angle. They later show up as bridesmaids at his wedding.
