* AdaptationDisplacement: Unless you paid attention to the opening credits, odds are you weren't aware that it's based on a novella by Samuel Hopkins Adams called ''Night Bus'', which was printed in ''Magazine/{{Cosmopolitan}}'' in 1933.
* AlternateCharacterInterpretation:
** Given how quickly Ellie falls for Peter, one could interpret her marriage to Westley as her taking the first option she could to escape from her oppressive father--and thus never seeing Westley as anything except an escape route. Then when she meets a man she actually likes, she realises she has no use for Westley.
** It's possible Alexander Andrews had no idea his daughter felt so stifled by being raised around bodyguards, making him InnocentlyInsensitive. He could have attributed her little acts of rebellion as typical teenage stuff, and doesn't suffer a HeelRealization until Ellie literally jumps off a boat, swims to shore and hitch hikes all the way across the country.
** Ellie almost overnight goes from IceQueen to GenkiGirl after the Walls of Jericho scene (something Peter lampshades). This is after she's found out he's a reporter. Is she intentionally acting as nice as possible to make sure he doesn't write anything too derogatory about her?
* AluminumChristmasTrees: Much is made of the fact that King Westley is a pilot. In the 1920's and 1930's aviation was a new and exciting field and pilots often did become celebrities.
* BestKnownForTheFanservice:
** If the movie gets mentioned, most of the time it's going to be for Creator/ClarkGable's shocking ShirtlessScene--where he wasn't wearing an undershirt. Legend has it that it caused undershirts to drop in popularity.
** There's also the famous, and often parodied, scene of Creator/ClaudetteColbert flagging down a car by lifting up her skirt and [[ShowSomeLeg exposing her bare leg]].
* EndingFatigue: Everyone knows how a film like this is going to end, so the ThirdActMisunderstanding really does drag out a good ten minutes longer than it should.
* EnsembleDarkhorse:
** Oscar "Believe You Me" Shapeley is played to comedic gadfly perfection by Roscoe Karns[[note]]His son Todd Karns went on to make a prominent appearance in another Creator/FrankCapra classic, as Harry Bailey in ''Film/ItsAWonderfulLife''[[/note]], and you might find yourself wishing he hadn't left the story so early.
** Alan Hale Sr. as the driver who picks up Ellie and Peter when they hitchhike, and constantly bursts into song for no particular reason.
* JerkassWoobie: Peter comes across as a dick to modern audiences, but it's heavily implied that he's never known any kind of love before--or never been able to make a relationship work. The Woobie part increases when he hears that Ellie has gone back to her father and husband.
* OnceOriginalNowCommon:
** To a modern viewer, it can play like a film that just strings together almost every possible clichéd RomanticComedy and RoadMovie trope. Of course, it actually [[TropeCodifier codified]] (if not [[UrExample invented]]) most of them.
** It also might seem familiar because Creator/AlfredHitchcock openly borrowed elements from it for some of his influential early {{Thriller}} classics. ''[[Film/The39Steps1935 The 39 Steps]]'', ''Film/TheLadyVanishes'' and ''Film/{{Saboteur}}'' all pair charming Peter-like guys with uptight Ellie-like women and send them on a journey together.
* ParodyDisplacement: Today, Gable's character munching on a carrot would likely be thought to be a reference to WesternAnimation/BugsBunny, for whom it is a defining element of his character. In fact, Bugs doing this is a reference to ''this'' movie, which is nowhere near as well-remembered.
* SignatureScene: The hitchhiking scene. It helps that Creator/ClarkGable's delivery while eating a carrot is suspected to have been a major influence in the creation of WesternAnimation/BugsBunny.
* UnintentionalPeriodPiece:
** It's fascinating to see how a RoadTripPlot plays out in an era when car ownership was far from universal, and when train travel was a bit of a luxury, and air travel was out of reach of all but the wealthy, so bus lines were the most affordable way to travel long distances in America. And bus trips had their own little rituals, like stopping for meals, people walking down the aisles hawking items for sale, or singalongs. And also, it's an era when motels had detached cabin rooms and community showers.
** TheGreatDepression is hinted at, with the other guests at the auto camp presumably being displaced migrants, and the hobos riding on the freight train that halts the cars in the climax.
* UnintentionallySympathetic: It's hard not to feel a little bit sorry for Westley when Ellie runs out on their wedding ceremony literally during the "I do"s. It does get mitigated a bit when Alexander pays him a very nice $100,000 for the annulment.
* ValuesDissonance:
** Peter opines to Ellie's father that she should perhaps be "slapped around a little," which doesn't affect her father's view of Peter at all (probably because it's entirely unclear whether he's serious, being hyperbolic in his frustration, or metaphorically saying that she needs more structure in her life).
** Also, not a lot of of romantic comedies are likely to start from a pretty serious blackmailing these days...
** There's also Peter spanking Ellie while carrying her across the river...
** Peter and Ellie have to pretend to be husband and wife whenever they stay anywhere, because no respectable place would take in an unmarried couple. Even though the audience knows Peter and Ellie won't have premarital sex, the implication is there.
** And notably despite pretending to be a married couple, both rooms they rent have separate beds. The Walls of Jericho gag wouldn't be possible in a film made away from the Hays Code's strict censorship about sexual content.
* ViewerNameConfusion: The credits and the screenplay both put two E's in Oscar Shapeley's last name, but it understandably often gets spelled the same as the word "shapely" (Shapeley making a pun on his own name and "shapely" doesn't help)
