Actor Allusion: Shun calls her manager "Sherlock" when he's stumped by how one of the cars could've been sabotaged so as to blow up so easily. The manager is played by Benedict Cumberbatch.
Emma Watson (Patricia Fields) has definitely been familiar with someone named Harry before, though that time it was a friend, and not a sibling, that bore the name. Also, her mother's maiden name was Granger.
Not exactly an actor, but Stefano Mainetti, who scores these two films, also scored Zombi 3 D, which features a song he wrote called "The Sound of Fear". The same song plays in the first film during the Magnificent Trio's first fight simply because Kae wants the DJ to set the mood for the fight.
Rupert Grint actually learned from when a plant nearly suffocated him for flailing around too wildly; in fact, when stuck in cake that functions the same way he just remains calm throughout.
Adaptation Dye Job: Patricia's hair is dirty blonde in this version. It still becomes cerise when she transforms into Cure Tora.
Avoid The Dreaded G Rating: Good God, does it ever! Apart from Obligatory Swearing, there's also a few fight scenes that have been brutalised, to the point where one scene infamously has Cure Tora stabbed by her own shuriken after her powers had been severely weakened. No blood is shown, and the shuriken dissolves upon impact because her powers are so weak by that point, but this is Played for Drama for all it's worth, and it's very intense, not to mention one of the most violent scenes in the entire film. While not nearly as violent, the Cures' initial scuffle with Kamryou's "Clayface" Dogou is certainly a bit bloodier; when Cure Draco's mist barrier is shattered by a burst of wind from the Dogou, all three Cures are actually bleeding in some areas as a direct result (the source material merely makes reference to "damaging water"). Of course, even the source material is guilty of this, as demonstrated with infrequent use of the word "asshole" throughout the series, among other factors.
Badass Longcoat: Both Cure Tora (post-upgrade) and Licht Panzer wear one. Cure Tora's looks like a brighter and frillier version of Maka Albarn's own longcoat. Cure Kame also wears one as part of her disguise when first infiltrating Club Full Moon with the rest of the Cures.
Bad Bad Acting: While disguised as a zombie, Patricia wanders over to a Roadham Public student with a Zombie Gait and this cheesy one-liner:
Patricia: I'm coming to get you, Barbara!
Beauty Brains And Brawn: Helen's the beauty, Isabelle's the brawn, and Patricia's the brains. This is brought up when Muse commends Patricia for her brilliant idea about sending a Xanatos Backfire upon the Master of Disguise they're about to fight, Tamakushi, by trying to beat her at her own game. In keeping with the source material, Helen's also got some shades of brains (which is why her sister Clara recommended her for Mirai in the first place), and Patricia has shades of beauty (helped by her serene sophistication).
Bifauxnen: While not actually one per se, some of Patricia's disguises give off such an impression.
Bigger Than Jesus: Bailey accuses Emmy of calling the light music club this at the end of an Arson, Murder, and Jaywalking listing of the Body Snatcher's offenses shortly before the Body Snatcher (who happens to resemble Emmy) shows up.
Black Comedy: The Magnificent Trio is portrayed in this manner.
But for Me, It Was Tuesday: The line (and the lines leading up to it) are paraphrased by Aseimera and Cure Lepus during the opening credits sequence. Lampshaded by Cure Tenma: "Quit the M. Bison act and come at us for real!"
Cassandra Truth: Both Harry and Patricia acknowledge they'd be likely to get Cross Cast Roles in the school musical. It's then stated that their roles haven't been chosen yet. When the roles are chosen a few scenes later, it happens exactly as they predicted.
Harry: With my luck, I'd probably wind up playing a young girl. [a couple of scenes later] Patricia: With my luck, I'd probably wind up playing a handsome boy.
Chekhov's Gun: The male uniform at the ballet school the Cures pass by on the way to Western Paradise is worn by Patricia when she shows up to confront Tamakushi as part of her plan to beat the Master of Disguise at her own game.
Country Matters: It's implied that Isabelle was going to use the C word on Patricia just as Helen's outburst at Western Paradise started.
Curse Cut Short: Kae at the end of the bar brawl scene. "Bring it on, you little mother—" Cut to the outside of K. Daniel Fields Mirai Private Academy as the Cures return the lucky objects she had stolen. Later, as tensions increase between the Cures, Isabelle tries to call Patricia the dreaded C word when Helen starts yelling at them. She cuts herself off mainly because a Sound Effect Bleep was in progress.
Isabelle: Bloody hell, the Wing Girl's been trying to include you, even though it's blinking obvious you're pissing her off too, so you could at least be grateful to her instead of being such a cu— Helen: STOP IT! I'm sick of this! All you've done this whole trip is act like a complete and total jackarse! She has feelings too, dammit!
Dragged Into Drag: The obvious outcome of a "Loser Wears a Dress" bet between Sean and Harry. Harry loses, and is thus stuck wearing the Mirai female uniform for the next day. In fact, Harry is quite the victim of this trope, having previously been roped into a Fashion Shop Fashion Show by Naelee and Chris and forced to try on pretty dresses.
Early-Bird Cameo: Victoria, first via mention by Cure Ushi in the opening credits sequence, and then more formally at the racetrack.
Every Car Is a Pinto: Some cars tragically did not survive Seimono's interference with the race (including the car Cure Tora used to win the battle for the Cures when it was grazed in the rear by another car, but it was due for decommissioning anyway). Thankfully, not only was Vic's car still intact afterwards, there isn't even a death toll resulting from the confrontation.
Fandom Berserk Buttoninvoked: Parodied when Helen calls "Baba O'Riley" by The Who "Teenage Wasteland" and Isabelle corrects her right after pointing out that the song's being used as the morning bell at one point.
Fashion Shop Fashion Show: Done here too, except this time it's a gag involving Naelee and Chris. In her usual scatterbrained fashion, Naelee actually orders Harry to come along and try some clothes on of her choosing. When he tells Patricia about his experience afterward...
Getting Crap Past the Radar: While disguised as a sophisticated Club Full Moon patron, Cure Draco tells Kae a joke. We only hear the first line ("A man walks into a talent agency...") and the punchline, but those are enough clues to tell you that the joke she's telling is actually The Aristocrats. Even Cure Kame is surprised that she'd have so much potential for such a mouth. Cure Draco notes that it's all part of her disguise.
Gosh Dang It to Heck!: When she sees Helen glowing as the Cures are meditating, Isabelle actually yells, "SACREBLEU!" In the Italian version, she instead uses a native minced oath, "PORCA MADOSKA!"
Insult Backfire: Between Isabelle and Patricia when the latter shows up as Cure Tora for the first time:
Cure Kame: Why does your costume look very different than what we're wearing? Cure Tora: Why shouldn't it? At least I don't look like some Eas wannabe, the way I'm dressed. [Cures Draco and Kame exchange confused glances]
Then we get this bit when Tamakushi realizes that the male ballet student that had just shown up and confronted her is actually Patricia in disguise.
Tamakushi: So one of the alleged ballet students is actually a girl, and with two left feet? Cure Tora: In such a context, those would be the kindest words I ever heard from you. Tamakushi: Well played, Cure Tora. Well played.
Lethal Chef: Food seems to hate Isabelle to the point where just preparing crisps and dip will trigger the fire alarm. Of course, that's just an exaggeration on her part; she's just so bad at cooking she actually burned a can of spaghetti and meatballs in the microwave.
Master of Disguise: Tamakushi. Patricia figures out that the Cures can fool Tamakushi if they disguise themselves, as she demonstrates with an obvious disguise as a male ballet student. Nobody but Tamakushi was deceived.
The Cures wear outfits based on early costume designs from the source material, and Cure Tora's outfit here proves to be quite practical, as she's noticeably faster here than in the original fanseries. Once the Cures get their Cure Arms, their outfits add some homages to the designs ultimately used in the source material; for example, Cure Tora starts wearing a frilly Badass Longcoat over her existing outfit, and Cure Draco's costume adds white accents.
The original name for the source material was Mirai no Pretty Cure. This is how the Cures introduce themselves at first before switching to "Live in tomorrow, fight for today! We are Pretty Cure!"
Richard and May Deschanel cosplay as Cure Black and Cure White, respectively, in at least one scene.
Harry does what his sister does in episode 7 of the source material during a depression, but in his case it's actually because of a "Loser Wears a Dress" bet with Sean.
Non Uniform Uniform: The regular Mirai students wear the same parochial uniforms as in the source material; the Fields siblings wear gray gakuran that, instead of a military jacket, incorporates a tunic.
Not so Above It All: While she doesn't really like being showy, Patricia is the first to admit that when dealing with Tamakushi, a good strategy would be to try to beat the Master of Disguise at her own game.
Not So Stoic: The first indication of this is that Patricia actually reacts to the revelation that the Julianne that was at the podium at the moment isn't the real Julianne.
Patricia: Mum, what the bloody hell's gotten into you?
N-Word Privileges: Invoked by Patricia when she mentions that only a Yaoi Fangirl can ship two boys together. At the time, only she and Naelee knew Chris was actually a boy, but we're never shown concrete evidence that Chris is a boy until part 2.
Obligatory Swearing: Several characters swear more often than in the source material, particularly Patricia when she's in a bad mood or otherwise shocked or irritated. Isabelle in particular has her own sailor mouth taken Up to Eleven.
Painted On Pants: Patricia's disguise when confronting Tamakushi for the first time incorporates black leggings; judging from an earlier scene where the group passes by a ballet studio on Roadham's Main Street in the middle of a class, she's clearly disguised as one of the students there.
Paper-Thin Disguise: Patricia's disguise from Pretty Cure's second confrontation with Tamakushi is made obvious by her glasses and dirty blonde hair in a pixie cut. Tamakushi was the only one fooled, judging from her reaction when the Cures transform during the confrontation.
Hell, any time a Cure is disguised, the villains will never recognize them until their Cure forms emerge. Even the Magnificent Trio has one hell of a problem figuring out who those three loudly-dressed interlopers at Club Full Moon were, particularly after the Cures show up without their disguises. Cure Tora in particular is all too willing to keep up that particular charade even undisguised:
Even Hinyu, the smartest in the Black Triumvirate, doesn't realize that Patricia was impersonating a zombie; while others catch on that she's cosplaying as Johnny from Night of the Living Dead when she opens her mouth, he simply assumes that "Johnny" was in the wrong movie:
Pink Is For Sissies: Inverted; the most serious tomboy in the group, Isabelle, is actually quite fond of the color pink (no wonder she can sympathize with Chris following an Unsettling Gender Reveal later on), while the girliest girl, Helen, doesn't like pink at all, as demonstrated with her words following a Gilligan Cut that puts her in disguise as a ballet student (which obviously has her wear a pink camisole leotard and tutu).
Precision F-Strike: Muse is slightly more aggressive with the language here—in fact, her first line has her call a Body Snatcher an "evil bitch". She also tells Tamakushi that Helen is just about to "kick... [her]... arse." Also, Patricia yells "Holy shit!" in surprise upon finding out the Magnificent Trio stole a cat statue containing her father's ashes. She's also visibly irritated as she calls Tamakushi "that bitch" while expositing to the Cures how her mother knows about them. She only uses profanity gratuitously a few times throughout the films, each time with an irritated tone in her voice.
Patricia also calls Isabelle a bitch after Helen's outburst. She definitely looked hurt when she called Isabelle out on her abrasiveness, and it's definitely more profound than when she called Tamakushi a bitch.
She winds up topping herself to make more obvious an Out-of-Character Moment where she's more fired up than usual and determined to bring down the "teacher" that dared hurt her feelings in front of the class: "I'm going to show that punk who's boss, that the Fields dynasty is not to be fucked with." Helen is shocked that she'd use the F word even when she's that angry.
Julianne tells Helen to find out "what shit went down" that caused Patricia to skip school in one scene in Part 1.
Proper Tights with a Skirt: Inverted a few times by Harry, most notably with his Cure Soul cosplay during K. Daniel Fields Mirai Private Academy's school festival. Helen plays this straight with a few of her own outfits, as does Muse. Chris is also an inversion.
Quicksand Sucks: Not only imported from the source material almost verbatim, but also the word "quicksand" is mentioned at least a couple of times by the characters during the scene. Both Cures Draco and Tora stay calm while stuck in the cake Dogou, which functions as the quicksand, but Cure Kame managed to flail around so wildly she's actually up to her neck within a few seconds.
Reality Is Unrealistic: The screenwriter has himself acknowledged that if Helen Wing was a real person, her friends would choose Clara over her. What happened between him and several members of the Curefic community may have something to do with this statement.
Recycled Soundtrack: Apart from portions of Stefano Mainetti's Zombi 3 D score, other pieces of music show up sometimes. For example, the theme from Suspiria plays several times throughout during meditation scenes or when a character has a flashback or is mentally disturbed (e.g. when Patricia inhales the spores sent her direction by Tobi and starts hallucinating as a direct result), and "Kitri's Solo" from Don Quixote plays as Helen and Patricia prepare the back gardens at the Deschanel residence for Andie Deschanel's wedding.
Rei Ayanami Expy: Patricia, whose looks actually resemble a cross between fellow Rei Ayanami Expy Yuki Nagato and Sam. Helen calls her on it: "Who does she think she is, Yuki Nagato with a dye job?"
Retirony: Applied to cars in one scene. That car that got grazed and incinerated after Cure Tora defeated Seimono and Kamryou with it? It was due to be decommissioned anyway.
Rule Of Cool: Isabelle's first fight literally takes place on the racetrack. Seriously, it's still very early on and already the fights are getting stylised!
Rule of Three: Used twice in the same scene. The first time is when Helen Bright Slaps Patricia three times during her pep talk. The second time pops up seconds after the third Bright Slap, when Helen does a Title Drop for episode 7 of the source material:
Helen: The truth is, we like you. We like you, Patricia. We like you!
Seriously, around the time Helen started feeling insecure about herself and perceiving Clara is better than she'll ever be, the author started beating himself up, finally acknowledging that he'll never be able to catch up to the source material or its author in terms of quality and that he may as well turn his own script into a quality trainwreck in light of how quickly shit went down in the Pretty Cure fan community in Real Life, to the point where the results of Helen trying to improve are little more than a fairy tale ending to such a situation as that.
Technology Porn: Both in front of the camera and behind it; for example, the framerate is 48fps, portions of the film are shot in IMAX 3D, and Calvin is quite the tech wizard.
Tights Under Shorts: Worn by Patricia as Cure Tora. The trope name is actually used by a demon to describe her outfit when the Cures first travel through the Demon Empire (to recover a bunch of stolen lucky objects).
Demon Who Trips Kame: And you! The girl wearing striped tights under shorts!
After getting her Cure Arms upgrade, Helen as Cure Draco starts wearing Tights Under Modesty Shorts.
True Blue Femininity: Which is why Helen's upset at having to wear a pink leotard and tutu for a disguise.
Unsettling Gender Reveal: Bailey does this to Helen in his first scene and had also done it to Calvin once before. In Helen's case, it's Calvin who drops Bailey's Bridget. Vic also does this to Helen while the Cures are in Julianne's office expositing what had been going on to her. Patricia also does it inadvertently to Tamakushi early on; her disguise didn't fool Helen, Isabelle, and Muse for one second, and her intention was not to fool anyone.
Vanity Plate: It's actually scripted and looks kind of like a less sci-fi and more fantasy variation on the Disney logo seen in TRON: Legacy. In a more subtle example, the BBC Video theme from the early '80s, referred to here as "BBC Video Synthesised March in A Major" (to indicate which variation of the jingle plays), plays as Julianne (actually Tamakushi in disguise) walks onto the stage to give her orientation speech to the new students.
Whole Costume Reference: Cure Tora's disguise at Club Full Moon is the same one used by Gadget in one scene in Inspector Gadget 2. Complete with the fake moustache. It's mentioned that she's the one wearing the disguise because Isabelle (the Shorttank on the team) had grown her hair out years ago.
Who Wears Short Shorts?: As with the source material, Isabelle makes a habit of it; the script even goes so far as to describe her as wearing her bike shorts under her initial formalwear just to make it as clear as it gets.
