* AnimationAgeGhetto: Oddly enough, a positive example. It was intended for adults and teenagers, but only became popular when it was released on home video and allowed baby boomers to introduce their kids to Music/TheBeatles through a trippy cartoon.
* SugarWiki/AwesomeMusic: It's Music/TheBeatles -- go figure.
** Specifically "Hey Bulldog" and "All Together Now": songs that had been relegated to the archive bin and otherwise wouldn't have seen the light of day. They're considered fan favorites.
*** "Hey Bulldog" is awesome in a meta was as well for being what those present at the time of its conception refer to as the last time The Beatles were a complete band and not just four people with bloated egos.
** Also "Only a Northern Song," Harrison's swipe at not getting more record time, gets it's moment to shine on the soundtrack.
** George Martin's score is no slouch, especially considering [[GenreRoulette all of the musical styles it covers]].
* BigLippedAlligatorMoment: Oh, where to begin! Ringo's entire house could be called a Big Lipped Alligator MANSION.
* BrokenBase: The Beatles' voices. Some find their deadpan reactions to ''everything'' to be part of the humor, others are bothered by it sounding "bored."
* CultClassic: The story is very simple and the film didn't do very well at first, but it is filled with very surreal imagery which attracts people to it.
* HarsherInHindsight: The clock in the Yellow Submarine speeds up to the year 2009, which only half of the band (Paul and Ringo) would live to see.
* HilariousInHindsight: When George sees that the car changes colors, he says, "It's all in the mind." Guess what made it into the ''VideoGame/ParappaTheRapper'' series nearly 30 years later?
* PeripheryDemographic: As mentioned above, the movie was going for a young adult audience but was much more popular among gen x-ers and millennials who's parents used this movie to introduce them to the Beatles' music.
** [[WordOfGod John claimed in one of his last interviews]] that while raising Sean, he and Yoko deliberately tried to keep John's Beatles history away from him, and played down being a millionaire pop star. It was only when Sean saw ''Yellow Submarine'' for the first time while at a sleepover at a friend's house that Sean recognized his dad in the film, and thus his role in the Beatles.
*** It went like this: "[[SugarWiki/FunnyMoments Dad! Why are you in a cartoon?]]"
* TearJerker: The "Eleanor Rigby" sequence manages to make the song even sadder and more depressing than it already was, which is [[UpToEleven no mean feat]].
** As the song Nowhere Man finishes Jeremy is seen sadly waving to the retreating figures of the Beatles who were going to leave him behind. He spins and he looks more depressed until he starts sobbing. [[SugarWiki/HeartwarmingMoments Though at the end Ringo was the only Beatle to take pity on Jeremy and offers him a ride with them which he gladly accepts]].
** Aged-down Ringo crying "I want me mum!"
** When Ringo goes missing in the Sea of Monsters.
** The sad, cold, statue-infested wasteland the Blue Meanies have turned Pepperland into.
* UglyCute: Jeremy.
** Many of the monsters who appear in the Sea of Monsters, including the one that briefly gets into the submarine.
* VindicatedByHistory: The film was initially a flop and killed the non-Disney feature animation market for years. Animator Creator/RichardWilliams, a fan of the film, claimed that the [[LimitedAnimation jerky, start-stop animation]] was to blame--it must have been, since Music/TheBeatles were at the ''height of their popularity'' by this point! That said, it has gained a CultClassic following over the years.
* WhatDoYouMeanItsNotForKids: A less extreme example. It ''was'' intended for older audiences, but there's nothing too vulgar about it that would keep kids from watching, which may be why [[PeripheryDemographic it's become such a popular way for parents to introduce their kids to]] Music/TheBeatles.
* WhatDoYouMeanItWasntMadeOnDrugs: In his book ''Up Periscope Yellow'', [[WordOfGod Al Brodax]], the man behind the production, who wrote or co-wrote most of the non-musical sequences, swears the only time he ever had drugs was in a meeting with John Lennon ''after'' he'd finished the script.
** In the behind-the-scenes portions of the DVD, it's revealed that while the animators never did drugs, they would often return to work a little drunk after having a few too many pints during their lunch break.
