- Award Snub: This album lost the Grammy for "Best Performance by a Vocal Group" to a group called the Anita Kerr Singers, whose album We Dig Mancini never even placed in the Top 40. Tellingly, Anita was vice president of the Nashville chapter of the NARAS in the mid 60s.
- Awesome Music - Should go without saying in a Beatles movie!
- Big-Lipped Alligator Moment:
- "The Exciting Adventure of Paul on the Floor", in which Paul shrinks to a minuscule size and has a brief exciting adventure on the floor.
- Intermission. Seven seconds of pure "what the heck was that?"
- The film's dedication to Elias Howe, inventor of the sewing machine.
- Covered Up: "Act Naturally", and to a lesser extent "Dizzy Miss Lizzy".
- Fridge Logic: Invoked. How does owning a ring that can't be removed from one's finger help one gain global domination? Who cares! The people chasing after it are clearly raving bonkers and desperate for anything.
- "Funny Aneurysm" Moment:
John (choking): It's me, you fool!George (teeth gritted, still strangling him): Oh! Sorry!
- Seeing John Lennon being threatened with a gun, especially since Foot actually fires it right at him, of all people, though it jams. Also, seeing George Harrison attacked with a melee weapon in his own home now seems very wrong.
- The Beatles are eventually told that the "sacrifice" will involve Ringo being "disemboweled," which is squicky enough. But it gets more uncomfortable in light of the major surgery poor Ringo had to undergo in 1979, where a significant portion of his intestine was removed—ironically, to save his life.
- Likewise, "Is it habit forming?" is harder to laugh at after reading about Ringo's frightening twenty-year battle with alcoholism and cocaine addiction.
- The scene where a bunch of vaguely Middle Eastern/South Asian cultists are rounded up and put into a prison camp and a Caribbean island.
- George saying "I've never seen any drummers with one, you know..." doesn't seem as silly in light of what happened to Rick Allen.
- Juxtapose the Beatles' concern not to step on shrunken Paul as "it's his best suit", or George cracking on Paul's goofy "Indian scout" delivery when he discovers fake footprints on the road in the Bahamas, by saying, "Don't encourage him. You've got the part, Paul", with the band's later Creative Differences with Paul five years later in Real Life, to say nothing of the earlier scene where George lunges for the throat of one of the bad guys and gets John, instead.
- Hilarious in Hindsight:
Paul: But is it mainlining, or habit-forming?George: (sticking gum in his mouth) Not as long as you don't swallow it.
- Given that it has the Beatles tangling with an evil quasi-Hindu cult, it's ironically funny that this is the film that got George Harrison, and the rest of the guys through him, interested in Eastern religion.
- Ringo, George, and John's disguises in the airport make them look much like they would later in life.
- Everything about the Beatles being on the run from (essentially) Indians and making (joking) comments about their 'filthy Eastern ways', considering they would later embrace that culture. In particular, a scene where the cultists quickly replace a band in a restaurant and start playing an Indianised instrumental version of A Hard Day's Night. In fact, George Harrison first got interested in the sitar seeing it used in that scene.
- At a certain point, the Beatles dress as a military band...
- Contrast the band members' stories that they were stoned on marijuana when they filmed the movie, with this bit of dialogue, as Ahme is attempting to inject Ringo's finger with a formula designed to shrink his finger so that the ring will fall off:
- The band's attempts to induce Ringo to part with his ring finger, since they figure he doesn't need it to play the drums. In 2006, Capitol Records edited the cover of a Beatles boxed set they were releasing, clumsily airbrushing the cigarettes out of the band member's hands. The result was that Ringo lost two fingers.
- The movie's especially funny in light of the fact that The Beatles later tried to get the rights to make their own film version of The Lord of the Rings (no, really). They probably figured they had experience acting in a film about a ring that all the bad guys are trying to take...
- In the Beatles' home, Paul's organ has Superman comic books on the sheet holder. Richard Lester, who directed the film, later directed half of Superman II as well as Superman III.
- Ringo says "There's more here than meets the eye..." after the attempt in the bathroom.
- The repeated bondage Ringo ends up in makes it just a bit funnier in his TV movie "Ringo," when he tells a female cop upon being handcuffed, "I'm not usually into this, but I could be," and his even later music video series "The Cooler" an absolute riot. Apparently the shrinking potion wasn't the only thing that was habit-forming.
- This wouldn't be the last British comedy with a seconds-long intermission.
- Ho Yay: John and RingoRingo: "What was it that first attracted you to me?"John: "Well, you're very polite, aren't you?"
- So Bad, It's Good: It was supposed to be, but not necessarily for the reasons that it actually is...
- This Is Your Premise on Drugs: Literally - the Beatles willingly admitted that the whole movie was filmed "in a haze of marijuana smoke." Just listen to John's awkward laugh when Ringo's finger is magnetized to the ceiling of their elevator as evidence of how checked out they were.
YMMV / Help!
