- Adaptation Expansion: The plot about Charlie Brown entering a spelling bee (and virtually all the dialogue and Chuck's inner monologue at the beginning of said spelling bee, as well as his inability to remember the "I before E" rule) is taken directly from the comic strip, but in the strip he only got to the first round as he blew the very first word he was given.
- Champions on the Inside: Averted BIG TIME. Charlie Brown is devastated over his loss and gets absolutely no hero's welcome or even consolation for his efforts. Then again, no one is angry with him - even Linus tells him that everyone ''missed him'' at school.
- Completely Missing the Point: Charlie Brown fails to realize he not only won the state Spelling Bee championship but he came in second in the National championship.
- Covers Always Lie: The DVD cover shows Lucy clutching Charlie Brown's arm and staring up at him adoringly. Not only is the whole movie about the ways in which she ruins his life (and no Jerk with a Heart of Gold moments, either), this also makes no sense if you know a thing about Lucy.
- Disney Acid Sequence: A lot of the musical numbers fall under this.
- Establishing Character Moment: The dynamic between Charlie, Linus and Lucy are established in the very first scene. Lucy comes off as the authoritarian, Linus sees archaic, intellectual objects in the clouds, Charlie sees just a duckie and a horsie.
- Failure Hero: Charlie Brown. Of all the Peanuts animated specials and movies, this is the one that really hammers in what a miserable failure he is.
- Freeze-Frame Bonus: While Peppermint Patty's "official" filmic debut is in Snoopy Come Home she can actually be spotted twice in this movie, as one of the kids cheering for Charlie Brown. The first time (right before the song Champion Charlie Brown) she's easily spotted jumping up and down together with Frieda, Shermy, Pig-Pen and 5, and the second time (when Charlie Brown is about to board the bus) she can be seen in the crowd, holding up a sign saying "CHUCK."
- Getting Crap Past the Radar: Near the end of the movie, Sally wants to know whether Linus is going to take her to an R-ratednote movie. "For mature audiences only."
- The Great Politics Mess-Up: A minor one. When Linus is describing what he sees in the clouds, he mentions "British Honduras". You probably know it as Belize (the name changed in 1973).
- Heroic BSOD: Charlie Brown has one after losing the spelling bee.
- Limited Wardrobe: Lampshaded; we get to see Charlie open his closet to reveal a rainbow of shirt colors, then choose the yellow one he always wears anyways.
- Only Six Faces: Milder example - One of the contestants in the final spelling bee looks exactly like Schroeder, while another one is essentially Linus with blonde hair.
- Public Domain Soundtrack: In one scene, Schroeder plays most of the second movement (Adagio cantabile) of Ludwig van Beethoven's Piano Sonata No. 8 in C minor, Op. 13 (Sonata Pathétique), and during that time, many Disney Acid Sequences occur, which is pretty creepy.
- "The Reason You Suck" Speech: As with the comic strip, Lucy uses her function as "psychiatrist" mainly as an excuse to deliver these to Charlie Brown. Throughout their session, she tells him everything that's wrong with him in increasingly creative ways, until he storms out, feeling worse about himself than ever.
- Reluctant Gift: As Charlie Brown heads off to the national spelling bee competition, Linus gives him his Security Blanket for good luck. He looks away with a pained expression on his face as he presents it, and in fact fails to notice when Charlie takes the blanket and enters the bus, so Linus remains holding up nothing and saying "Here!" as the bus drives away. Eventually the absence of his blanket gets to him and he goes to New York to get it back.
- Second Place Is for Losers: Poor Charlie Brown, yet again...he was so close!
- Spelling Bee: A major plot point.
- Status Quo Is God: The rare positive example of the trope, with An Aesop: "Life goes on, no matter how badly you may think you messed up."
- That Cloud Looks Like: British Honduras, and/or a ducky and a horsie.
- Wham Line: "The world didn't come to an end."
- When He Smiles: Mentioned in the A Boy Named Charlie Brown song:Maybe it's a kind of magic
That only little boys can do.
But seeing Charlie smile,
Can make you stop awhile,
And get you feelin' glad you're you.
- Written Sound Effect: When Lucy shows Charlie Brown a slideshow of his flaws, she somehow captured the word "POW" on the slide showing his lack of style.
- X Must Not Win: The universe's attitude towards - who else? - Charlie Brown; he screws up spelling "beagle" due to a combination of Snoopy (who is a beagle) following him along and worry over Linus getting angry at Charlie Brown for a trivial reason.
- Yank the Dog's Chain: Happens three times. Most of the things Charlie Brown tries, he fails utterly at — but there are three occasions when he thinks he might make it.
- The first time is when the movie continues the Running Gag from the strip of Lucy goading him into kicking a football but yanking the ball away from him at the last second. This time she has a bonus surprise; she set up a video camera to record the ordeal and shows him his failure in slow motion while delivering a "The Reason You Suck" Speech.
- The second time is the movie's climax, when Charlie Brown has managed to become one of the two finalists in the spelling bee, and after having managed to spell a whole lot of difficult words right, gets a really easy one — "beagle." Which he has forgotten how to spell.
- The third time is the final scene in the movie when he tries to sneak up on Lucy to kick the ball again. Turns out she knew he was sneaking up on her, and once again the ball is yanked away and Charlie Brown falls flat on his back. However, it comes off as sort of heartwarming, letting Charlie know that nothing's changed, for good or ill.
- Your Head A Splode: This (symbolically) happens to the spelling-bee contestants whenever they get a word wrong. Even funnier because the head usually assumes an Oh, Crap expression just before popping like a balloon.
