Creator/JackBlack plays Hal Larson, who, [[FreudianExcuse unconsciously traumatized by his father's death at age nine]], is one of the shallowest men in the world. Until one day when, trapped in an elevator with Tony Robbins, he is unknowingly hypnotized so that, every time he meets someone new from that point onward, he will see their "inner beauty" instead of their real appearance.


Most notably, he meets a woman named Rosemary, played by Creator/GwynethPaltrow who, to him, looks like the most beautiful woman in the world because of her great inner beauty. In reality, however, she's extremely fat. It's not the only cognitive dissonance -- far from it -- but it's the one that made the trailers.

!!This film provides examples of:

* AsHimself: Tony Robbins, Joshua "Li'iBoy" Shintani.
* BeautyEqualsGoodness: The movie's premise [[InvertedTrope inverts]] this. The better a person you are, the more attractive Hal perceives you as.
* BeautyInversion: A number of beautiful actresses wore makeup to appear ugly outside of Hal's "Inner Beauty Vision". The directors especially took flack for casting a skinny actress like Paltrow as a fat woman, but explained that it was easier for Paltrow to fat up (with makeup and a fatsuit) than it was for a heavy actress to slim down.
* BigEater
-->'''Rosemary''': I'll have a double pizza burger, chili fries, and a vanilla milkshake.
-->'''Hal''': Nicely done! I'll have the exact same thing.
* BitterSweetEnding: Rosemary, still hurt from Hal's recent behavior and actions, plans on going away on a Peace Corps mission even after Hal pleads for her not to go. [[spoiler:So he decides to go with her instead.]]
* BrawnHilda: After Hal loses his Inner Beauty Vision, the rotund housemaid whom he initially mistakes for Rosemary is named Helga.
* BrokenAesop: A film with an intended Aesop about how people should not be so shallow and judge people on the kind of person they are, not by how they look on the outside, but this loses some steam considering how many fat jokes it has at Rosemary's expense.
* {{Cameo}}
* ComplimentBackfire: When Hal meets Rosemary's mother he says, "I can see where Rosemary gets her figure." He intends it as a compliment because he sees both of them as slim women, not realising they're both quite overweight.
* ContrivedCoincidence: The movie is full of them, but the most prominent example is when Hal sees Rosemary for the first time (as slim-figured Gwyneth Paltrow, of course) walking into the clothing store, only to catch up with her and, after getting acquainted with her, later finds out she happens to be his boss's daughter.
* CursedWithAwesome: Basically, all the nicest and kindest people are identifiable on sight. Oh, and if you ever date one, they'll also be smoking hot.
* CutASliceTakeTheRest: Rosemary cuts off a "sliver" of a cake that's about 1/3 as big as the whole cake, and walks off munching on it like a Pringles chip.
* DoubleStandard: Looking the way they do, Hal and Mauricio really shouldn't have high expectations from women. They do give them both {{Freudian Excuse}}s for their hypocrisy, though; Hal is traumatized by watching his father die when he was young, who demanded on his death bed that his son be utterly perfectionist when judging women. Mauricio [[spoiler:is redirecting a bottled-up inferiority complex. He has a physical deformity himself that he can't get rid of (a vestigial tail at the base of his spine), but has chosen to see it as a weakness.]]
* FreakinessShame: [[spoiler:Turns out Mauricio has a tail.]]
* FreudianExcuse:
** Hal is shallow because of his father's dying words about appearance.
** Mauricio is shallow because of his [[spoiler:vestigial tail]], which shames him into avoiding meaningful relationships.
* GaussianGirl: Inverted and Subverted. After Hal's hypnosis is worn off, he puts Vaseline on ''his'' eyes to so that he won't be able to see Rosemary clearly. His vision is so blurry, he can't tell if Rosemary is attractive (to him) or not.
* GoldDigger: This is why Nurse Tanya Peeler, who is actually young and pretty, looks like an old crone to Hal. She's dating his friend, Walt, solely because of his money, and even confesses to Rosemary that the timing of their relationship could not have been better, [[KickTheDog just after she had broken up with her boyfriend]] and just after he had sold his company [[ItsAllAboutMe and had all the time in the world to go shopping with her etc etc]], which is really another way of saying she can now MOOCH off of him.
* HairOfGoldHeartOfGold: Rosemary is kind and generous with attractive inner beauty.
* HasAType: Initially Hal constructs his ideal image of a woman from bits and pieces of celebrities.
* IncorruptiblePurePureness
* {{Jerk with a Heart of Gold}}:
** Hal.
** Mauricio could almost count too, given that he develops some depth as the film goes on.
* LiteralMetaphor: When Hal describes Ralph as "[[PrettyBoy Pretty Boy]]" to Rosemary while dining at a restaurant, he also alludes to the ''metaphorical'' halo around his head to reiterate how divinely handsome and good he is. But since Rosemary is unaware of Hal's hypnosis, she tells Hal that he's the first one to ever call Ralph that, and furthermore, she thinks the "halo" he's talking about is, in fact, the psoriasis around Ralph's head, and she even tells that to Hal directly.
* LittlestCancerPatient: [[spoiler:A whole Pediatric Burn Unit of them.]]
* MeaningfulEcho: "Cuckoo!"
* MindRape: ''Unknowingly hypnotized?!''
** All Hal thought was that Tony Robbins did something to help him "score better with the ladies." He had no idea that it literally changed his vision.
* MinorFlawMajorBreakup: Mauricio gives a [[Film/MaryPoppins practically perfect]] girl the cold shoulder, passing up an opportunity to see a [[Music/TheBeatles Beatles]] reunion while George Harrison was still alive, ostensibly because one of her second toes is slightly longer than normal. Turns out however that it's because [[spoiler:he's ashamed of his own elongated tailbone.]]
* NiceJobBreakingItHero: Mauricio after he de-hypnotizes Hal. Made worse by the fact that he lied to Tony Robbins about Hal getting fired in order to get the words needed to break the hypnosis.
* {{Oireland}}: Rosemary's father to painful levels.
* PleaseDontLeaveMe: Hal does this towards Rosemary at the end of the film. [[spoiler:It doesn't work, though fortunately he had a backup plan, to simply go with her instead.]]
* PrettyBoy: What Hal sees Ralph as.
* RunningOnAllFours: The character of Walt, played by Rene Kirby who has spina bifida and really does walk on all fours in real life.
* SeinfeldianConversation: Hal and Mauricio have one.
-->'''Mauricio:''' I'm probably more immature than you, but at least I have a bigger willie.\\
'''Hal:''' Yeah, bigger than a mouse's.\\
'''Mauricio:''' What the hell was that?\\
'''Hal:''' I said your willie's--\\
'''Mauricio:''' I heard what you said, but it took you, like, eight seconds. You can't come back with a comeback after eight seconds. You got three. Five, tops. That's why they call it a "quip," not a "slooowwwwwp."
* SlidingScaleOfBeauty: Quite notably scores pretty evenly around the scale. The nastier girls (and Rosemary in Hal's eyes) are very pretty, while some of the characters are just average or flawed average, perhaps flawed pretty, and some of the nice girls are honestly ugly. Rosemary's two guy friends from the Peace Corps are overweight and/or unattractive yet are seen as intimidatingly handsome to a hypnotized Hal and the seemingly healthy-looking kids from the hospital [[spoiler: turn out to be burn victims]].
* StealthInsult: The bulk of this movie serves to be a backhanded compliment to unattractive people, basically saying their inner beauty compensates for their outer ugliness.
--> '''Mauricio:''' (to Hal after he reverses the hypnosis) You weren't irresistible to women. He [Tony Robbins] hypnotized you so that really ugly girls that you met from then on would, to you, look like supermodels.
** The exception to this trope, however, [[spoiler: occurs during the scene with the little girl in the Pediatric Burn Unit at the hospital when Hal goes back the second time, looking for Rosemary. [[TearJerker This is the defining moment in which he realizes that he doesn't need hypnosis to see the inner beauty in people]]]].
* TitleDrop: "Shallow Hal wants a gal", the incantation Mauricio uses to break the hypnosis.
* UglyGuyHotWife: Mrs. Shanahan, though overweight, is still prettier than her husband.
* TheUglyGuysHotDaughter: Subverted. Hal sees Rosemary as a slim attractive woman but she resembles her father's figure very much.
* UnsettlingGenderReveal: The hostess at the restaurant turns out to be a transgender person.
