Absurdly Cool City: Toronto, a city so cool that Animesque fights can occur in the coolest night clubs and at least one girl is so hot that ice and snow literally melt beneath her feet.
Accidental Misnaming: The Members of Sex Bob-Omb are the only people in the film that can seemingly say their band's name right. Even fangirl Knives is the slightest bit off every time she tries.
Adaptation Distillation: The movie pares down many subplots and extraneous characters (for example, the relegation of Lisa to the animation allows them to get rid of a lot of Volume 4 without impacting the plot too much), and compresses the time-frame to somewhere around four and a half weeks (Ramona re-dyes her hair every week and a half, and goes through three dye-jobs over the course of the movie), rather than the year-ish of the comic.
Adaptation Explanation Extrication: Without an explanation playing into the climax (as it did in Volume 6, which was being written while the movie was in production), the concept of "subspace" is essentially downgraded to a handwave for why Ramona appeared in Scott's dream. Subspace, and its random doors popping up, could probably have been cut altogether if it wouldn't have caused the fans to revolt.
Adaptation Dye-Job: Envy Adams is a redhead in the books and a blonde in the film. Knives also dyes her hair blue in the film instead of red. The back cover of book two shows Todd with brown hair opposed to the film's grey color (although that appears to be a literal dye-job). Also, Young Neil was blond in the books, but in the movie he is dark haired.
Age Lift: Inverted some of the characters are a year younger then the they are in the books such as Scott and Stacy.
Affably Evil: Lucas has shades of this, making small talk with Ramona after before tossing Scott into a castle, signing an autograph for Wallace, and remarking that Scott seems like a nice guy. This is a holdover from the comic, where he was more of an "edgy" than "evil" ex.
Bryan Lee O'Malley gave each of the principal cast a list of ten secrets about their characters not included in the original graphic novels. The actors have mostly been tight-lipped about these. Some secrets have come out:
Mary Elizabeth Winstead has revealed that Ramona's little brother died when she was younger, and she wears one of his shoelaces as a necklace in memory of him.
Aubrey Plaza mentioned in numerous places that Julie Powers had an unrequited crush on Scott in college, (one that possibly continues into the present,) which is why she's so hostile to him (especially if, like in the books, Scott's eventual girlfriend, Envy, was Julie's roommate). Bryan Lee O'Malley contests this as Plaza "making shit up", though Edgar Wright supported Plaza's claim when both were on the "Doug Loves Movies" podcast.
Mark Webber was told about Stephen Stills's homosexuality before it was revealed in Volume 6.note Although, as Stephen says in Volume 6, it's actually revealed in Volume 5 because Scott (and by extension, the reader) were too busy focusing on the Evil Exes situation)
All There in the Manual: The film makes vague references to the backstories of its supporting characters. The details given line up with what's presented in the graphic novels, so it can be inferred that those character histories can be taken as true within the movie's continuity as well. One assumes, for instance, that the reason the film's Julie and Envy seem close (at least, relative to Julie and everyone else) is that, as true in the books, they were roommates in university (though in the novels, Julie hated Envy at the time, and is only being friendly now because she's famous). Perhaps the biggest omission in the movies is the fact that Scott is the best fighter in the province. It makes sense that he can fight so well if you know that, but given it was a one-time line in the books and not in the movie at all, his combat prowess seems to come, not out of nowhere, but from playing video games.
And That's Terrible: When Gideon kicks Ramona, sending her falling down a set of stairs the announcer from "Ninja Ninja Revolution" repeatedly exclaims "Bad!"
Neil is featured more prominently in the film, being treated more as the band's roadie than as just a hanger on. He even takes over on bass after Scott quits.
Knives' role is also greatly increased compared to her role in the novels. As explained by Edgar Wright, Knives' arc in the novels reached something of a climax when she battled Ramona in the second volume; the film, by tying this into the final fight against Gideon, increases Knives' significance almost by accident.
Ask a Stupid Question...: Knives asks Julie if the music store has any Clash at Demonhead CDs. Julie's sarcastic response of "Did you check the section marked 'Clash at Demonhead'?". Furthermore, in her very first scene, Knives also asks Kim, "And you play the drums?" while Kim is sitting at the drums holding drum sticks.
Battle Discretion Shot: During the fight against Lucas Lee, the stunt doubles start ganging up and kicking the crap out of Scott, and Lucas himself walks off to get some coffee. The camera follows him for the twenty seconds it takes to get to the production assistant and get the coffee, and when Scott calls his name, the camera pans back over to Scott standing over the bodies of all the stunt doubles. No indication is given how Scott turned the situation around.
Becoming the Mask: Apparently, Envy, but Scott pierces the facade after the fight with Todd.
Scott: Yeah, well, you kicked my heart in the ass, so...guess we're even... Natalie. Envy: Natalie? No one calls me that anymore... Scott: ...Maybe they should.
Beware the Nice Ones: Scott, as shown in his first round at the Chaos Theatre. Okay, so he isn't exactly a paragon of virtue, but if this movie teaches anything about him that the comic didn't, it's that if you cross the line twice with him, things will definitely not be pretty. He even displays hostility towards his old band.
Big Damn Movie: With the title, sort of. The League of Evil Exes isn't exactly "the world," but one imagines the title says that to make it seem bigger.
It takes its name from the second book. The title probably deals with the fact that Scott is up against the world in a metaphorical sense. The fifth book is titled "Scott Pilgrim Vs. The Universe." by contrast.
The original title of the movie took it from the first book titled Scott Pilgrim's Precious Little Life but was changed later in production.
Bittersweet Ending: Particularly tricky example, since almost every element of the resolution has a good and bad interpretation, The League are defeated and Scott and Ramona are free to pursue a relationship less hindered by the ghosts of the past, they make a good couple to begin with and the continue screen suggests an intentionally ambiguous resolution. Our poor woobie Knives is left out in the cold, but, as she says, she's probably better off in the long run without Scott. The band lost out on their big break, but then again, being contracted to a guy like Gideon probably wouldn't have ended well anyway (and besides, there's all those coins left over in the Chaos Theatre to be scooped up). What kind of ending we have is all in how you slice it. Though there is an alternate ending on the DVD that has Ramona and Scott go their separate ways and while Scott goes off with Knives instead. Does't make the end any less bittersweet, but at least the alternate ending exists.
Bloodless Carnage: The film gets around this by having people explode into coinsnote If you look closely, it's actual Canadian legal tender when they are killed. Subverted when Scott cuts Gideon's face with the Power of Self Respect.
Bollywood: Patel becomes a Bollywood stand-in for the movie, indulging in a song and dance number when unleashing his mystical powers and modeling his mannerisms after various hammy Bollywood bad guys.
The film begins and ends with snippets of 8-bit music; it begins with the UniversalLogo Joke (see below), and ends with an 8-bit rendition of Sex Bob-omb's "Threshold".
Internally, the Street Fighter "K.O.!" announcements only occur on Scott's first and final victories.
The Alternate ending features Knives and Scott together playing Ninja Ninja Revolution.
Scott giving Neil his bass. Literally during the fight with Patel (by throwing it at him), then figuratively during the fight with Gideon (by officially giving Neil his spot as The Sex Bob-Omb's bassist).
In Scott's first fight with Matthew Patel, the latter yells Scott's name when he first arrives to fight. The same happens when Scott arrives at the Chaos Theatre.
Boss Battle: The Evil Exes, obviously. Conveniently, they all meet established boss tropes!
Boss Remix: "We Are Sex Bob-Omb" is redone as "We Are Sex Bob-Omb (Fast)" (faster and without vocals) and "Death To All Hipsters" (chiptune-style) for the Gideon fights.
Boss Rush: As might be expected from the previous list, the entire movie is kind of a film-style Boss Rush. The only mooks Scott ever fights are Lucas' stunt doubles and Gideon's random dudes who come out of nowhere.
Bread, Eggs, Milk, Squick: Ramona listing the various types of tea - "We have blueberry, raspberry, ginseng, sleepy time, green tea, green tea with lemon, green tea with lemon and honey, liver disaster, ginger with honey, ginger without honey, vanilla almond, white truffle, blueberry chamomile, vanilla walnut, constant comment and... Earl Grey."
Lampshaded by Scott: "Did you make some of those up?"
Wallace: Step up your game, Scott. Break out the 'L' word. Scott: Lesbian? Wallace: [exasperated] The other 'L' word. Scott: [beat] Lesbians?
And, much later, the payoff:
Scott: I'm in lesbians with you. Ramona:[beat] What?
Finalized by the final brick shortly after:
Scott: I said lesbians.
Bonus points for when he actually fights a lesbian.
Bring My Brown Pants: When Scott lands on the ground after being thrown high up into the air: "If I peed my pants, can we just pretend I got wet in the rain?"
When G-Man compliments Sex Bob-Omb on their set, the lead guitarist wets himself, though it's more from overwhelming joy than fear. From the look on his face he could be having a spontaneous orgasm, but that might have pushed the movie past a PG-13 rating.
Burning Rubber: In one scene, Ramona's casual skating cuts a melting trail through several inches of snow and ice. One wonders what would happen if she really booked it. This, in addition to her use of the Subspace Highway, is probably why she's such a good delivery girl. Of course, this is more likely meant to signify that she is smoking hot. As if anyone needed a hint.
Although commentary says this was done to give Ramona an air mystery and magic from the start.
Toronto Doubling: Averted — The movie is filmed in Toronto, set in Toronto, and stars an actor from Toronto. The fact that this is unusual is lampshaded while fighting the second ex: Scott gets hurled through the backdrop matte painting of the Empire State Building on the movie set. The CN Towernote For the uninitiated, it's an iconic Toronto landmark is briefly visible through the hole thus made.
"They make movies in Toronto?"
Call Back: A whole lot of stuff from the Ninja Ninja Revolution game (HUD elements and the announcer) appear again during the fight with Gideon and then Nega Scott's appearance is also a call back to the fact that Scott can't beat Nega Ninja in the game
Call Forward: the first time Ramona appears onscreen, the BGM is a pre-vocals version of "Garbage Truck", the love(?) song Sex Bob-Omb play at The Rockit just before Matthew Patel appears.
The Cameo: Thomas Jane and Clifton Collins Jr. as The Vegan Police.
Canada, Eh?: The most Canadianest movie in years. (Well, a few years.) The film, with American audiences in mind, lampshades the fact that the story takes place "In the faraway land of Toronto, Canada." Something the book does not.
However it is averted in many ways as well, with no stereotypical Canadian accents, Mounties, and Scott only says "eh?" once.
The Casanova: Both Scott and Ramona fit this trope in their respective circles. Having them fall for each other is somewhat played as Laser-Guided Karma.
Julie suggests early on that Scott is this (or was, prior to his breakup with Envy, and may resume the title if he courts Ramona while still dating a high schooler). She has the list of women to back up the claim, so Scott seems to be in denial about it.
Wallace seems to be more of a straight-forward example - he wrangles every guy he sets his eyes on (except Lucas Lee for obvious reasons), including Stacey's boyfriend. It's implied that this has happened before.
Stacey: Wallace! Again?!
Catapult Nightmare: The basis of a Running Gag. Though his dreams are never nightmares, they cause Scott to wake up by catapulting into frame, which then causes Wallace, Other Scott, and eventually Jimmy to be woken up in the same manner.
The Chew Toy: Both Scott (for his Jerk Ass leanings) and Knives, who goes through quite the Humiliation Conga (nearly injuring herself trying to look more like Ramona, then getting said highlights knocked out of her hair by one of the aforementioned girl's Evil Ex's) before establishing herself as an Iron Woobie and proving to be close to Scott and Ramona's equal.
Considered and averted. Word of God says Roxy and Envy were combined into a single character for an early draft, until the release of Volume 4 convinced the screenwriters to split the characters again. Might explain how Roxy inherits Envy's weakness from the graphic novel - the back of her knee. The entire Ramona against Roxy fight is basically the fight with Envy, right down to the dialogue.
Played out similarly with Gideon, Ramona's role in the final fight is actually reduced to the point of mirroring Envy's almost completely. She pretends to hug Gideon only to knee him and even uses Envy's "Let's both be girls" line.
Conditional Powers: Todd Ingram has telekinetic powers that only work if he remains vegan.
Cool Big Sis: Inverted. Stacey "Rated T for Teen" Pilgrim is 4 years younger than Scott but much more mature than him, and so Wise Beyond Her Years that Scott constantly turns to her for advice. She even calls him "little brother".
Plus, considering Anna Kendrick is three years older than Michael Cera, looks and acts like it, and is best known for her role in Up in the Air which paints her considerably more adult, it's an easy mistake to make.
Cool Sword: A couple: Roxy Richter has a studded belt/Whip Sword... thing, Gideon's cane sword and Digitana, Scott's Power of Love and Power of Self Respect.
Creator Cameo: Bryan Lee O'Malley (as well as his wife) appears at the bar of Lee's Palace after Sex Bob-Omb's performance.
Co-writer Michael Bacall is seen talking with Comeau at the opening party.
Second unit director Walter Gasparovich plays the director of Lucas Lee's film.
Credits Gag: Michael Lazarovitch is credited as “Some Guy”.
Crouching Moron, Hidden Badass: For the most of the film, Scott appears to be really wimpy and nonthreatening. However, whenever an Evil Ex shows up, Scott suddenly takes a level in badass and beats the crap out of them. This is a departure from the graphic novel, where it's explicitly stated early on that Scott is the "Best Fighter in the Province". In the movie, he could very well still be an accomplished martial artist, but his nebbish personality makes it seem unlikely.
Deadpan Snarker: Much of the supporting cast like to knock Scott down a peg, but Kim and Wallace are the new poster children.
Kim: That poster needs more exclamation marks.
Wallace: Is that girl a boy too?
Death by Adaptation: Crash and The Boys are killed by an errant fireball during the fight with Matthew Patel.
Death by Sex: Roxy, Sort of. Scott defeats her by hitting her weak point, which happens to be the inside of her knee. Apparently, this is an erogenous zone for Roxy, and results in an intense orgasm before she explodes into coins.
Death Glare: Todd's default expression. Takes the form of the Kubrick Stare when he's first seen, sans-smile. Kim Pine, especially as played by Allison Pill, looks like she could melt steel with her eyes much of the time, especially during the Battle of the Bands.
Envy's entire group does this in unison backstage when Knives tries to speak up. Topped off with a large "GLARE" subtitle above them.
Demoted to Extra: Kim Pine, compared to her more involved role in the books (mostly because her backstory has been moved to the [adult swim]Animated Adaptation). Envy Adams gets quite a bit cut out as well, since her fight with Ramona is cut and is compacted into Ramona's fight with Roxy Richter. She is completely absent in the climax and her role is merged with Ramona's. Richter herself gets quite a bit cut out; she almost got a complete axing when Edgar Wright considered depositing Envy into her role as Ramona's 4th ex. Nega-Scott gets the axe from playing a pivotal role in the books to being reduced to a mere punchline in the movie. Lynette Guycott although having a minor but pivotal role gets barely minutes of screen time, and her punching the highlights out of Knives' hair was designated to Todd. Finally the Twins are almost cut out entirely, as they have zero lines (their actors don't speak English), zero backstory, and probably the least screen-time of any of the exes, only seemingly being in the movie because they are exes number 5 and 6 respectively.
Scott: I dislike you, capiche? Todd: Tell it to the cleaning lady on Monday. Scott: What? Todd: Because you'll be dust by Monday. Scott: Um... Todd: Because you'll be pulverized in two seconds. And the cleaning lady... She cleans up... dust. She dusts. Scott: ...So... so what's on Monday? Todd: ...Because... it's Friday now... she has weekends off, so... Monday. (to Envy) Right?
Door Closes Ending: At the end, Scott and his love interest walk through a door to hyperspace and it closes behind them.
Double Standard: Wallace tells Scott to break up with Knives if he's going to date Ramona. Scott promptly points out that Wallace is dating two men. Wallace ignores him.
Wallace: I didn't make the gay rule book. If you have a problem, take it up with Liberace's ghost.
Considering the scene with all four of them at same time it can be fairly assumed that they all aware and it is a open relationship.
"Threshold", as well as its 8-bit chiptune version.
The Prodigy tune "Invaders Must Die" was featured in the trailers and is dangerously catchy.
Many have expressed a weird affection for Matthew Patel's out of nowhere Bollywood-style musical number "Slick" as well.
Black sheep, come home...
The nightclub fight. From now on, whenever two girls are fighting, try not to imagine that thump thump thump bass beat.
Eleventh Hour Superpower: The Power(s) of Love/Self-Respect, which take form as the sword Scott uses in the final battle. Neither of them actually last very long, although Self-Respect gives Gideon a run for his money.
Embarrassing First Name: Gideon is the only person in the film to call Kim Pine "Kimberly." Her look of distaste is amazing.
Everyone Went to School Together: Young Neil says that Scott, Stephen, Kim and himself went to the same high school together. Scott also went to college with Julie and Natalie. Ramona went to junior high with Matthew, High school with Lucas & Todd and College with Roxy.
Evil Counterpart: Subverted. Nega Scott turns out to be pretty much the same as regular Scott.
Further subverted if you think that Scott is a jerk, while Nega Scott seems like a genuinely nice guy.
Lucas Lee seems a lot like White Goodman. Both arrogant egotistical muscle-heads with their own crews and franchises who take towards trying to beat the protagonist. They also sound quite alike.
Kim Pine sounds monotonous for the most part and in utter contempt for the stupidity of her fellows. Much like Daria.
Extremely Short Timespan: Compared to the books, which takes place during the span of approximately a year, the movie condenses its events to roughly a month or so.
Fake Band: Several. Sex Bob-Omb (songs written by Beck); The Clash at Demonhead (song written by Metric); Crash and the Boys (songs written by Broken Social Scene); and the Katayanagi Twins (instrumental by Cornelius).
First, when Young Neil tells Knives after the Clash at Demonhead concert, "You should hear them live. They're much better live." (This is also Leaning on the Fourth Wall, since the "live" performance takes place in the film, not live.)
In fairness, Ramona was supposed to be more active in the final fight. The troubles of staging a four-way battle on a pyramid forced the filmmakers to cut back.
Faux Affably Evil: Gideon during Scott's appearance at the Chaos Theatre. He treats Scott like an honored guest and even offers him Coke Zero. Scott rejects Gideon's attempt at friendliness, which quickly causes it to vanish.
Felony Misdemeanor: "You made me swallow my gum! That's going to be in my digestive tract for SEVEN YEARS!"
"You punched me in the boob! Prepare to die, obviously!"
"Do you know how long it took to get all the evil ex's contact information so I can form this stupid league? Like two hours. TWO HOURS!!!
Femme Fatale: Envy Adams, taken to such a gloriously hammy extreme by Brie Larson that it becomes a parody.
First Girl Wins: Teased. The original ending until quite late in production of the film had Scott getting back together with Knives, but this was changed after O'Malley had a better handle on how he wanted to end the series.
Played straight, however, in the Lucas Lee movie (Cold Call) that Wallace watched.
Flat "What.": Stacey gives one when Matthew Patel starts singing. It's the only time in the movie anyone acknowledges that anything strange is going on. Of course, she is the Only Sane Younger Sister...
Focus Group Ending: Audiences didn't like the original ending with Scott and Knives getting together because, as Knives says in the ending actually used, she's "too good for him", and it made the whole fight for Ramona pointless. So the ending was changed and Scott and Ramona hook up.
Foreshadowing: The last thing Scott does before he begins fighting Ramona's evil exes is unplug his bass and throw it to Neil. Later in the film, Scott formally quits the band, and Neil replaces him as a direct result of Scott's fights.
During the title sequence, each billed actor has images of their character traits and motifs in the background during their card (corresponding numbers for the evil exes, cell phone battery for Kieran Culkin as Wallace, sai for Ellen Wong/Knives, etc.)
When Scott is asking people at the party for information on Ramona, one person say "She has men dying at her feet" which pretty much happens to Scott and maybe some of the other exes.
The one boss Scott can't beat in Ninja Ninja Revolution is the Nega-Ninja.
After the Roxy fight, Ramona grabs the back of her neck and we hear a metallic whine just before she tells Scott "I think we should split".
During Scott's fight with Matthew Patel, if you pay attention, one of the fireballs burns Crash and the Boys, turning them into skeletons; explains why Sex Bob-Omb won by default.
The excuses that come to Scott's mind in the form of a wheel of fortune when Ramona asks how old Knives is are mostly unreadable without pausing the movie. They include: "She's nobody", "She's forty!", "Idiot!", "No speaka English", "When's dinner?", "Uh...", "Tell Pac Man story", "No, you are", "Pass out" and "It was nothing".
In the record store, in addition to the "Pop/Rock" label you'll see in any record store, you'll also see things like "Math Rock" and "Sadcore", both of which are real sub-genres of indie rock.
In that same store the only visible CD between Knives and Scott when he breaks up with her is Beck's Modern Guilt. Funny coincidence, because Beck wrote and composed many songs for the movie, and performed the full version of the Ramona song.
During the scene between Scott and Ramona on the bus, look carefully behind each character's head when the camera focuses on them. All the lights in the background on Ramona's shots are X-shaped, while in Scott's shots they are heart-shaped.
Until Scott asks if they are actually dating. Then it's hearts on both sides.
During the fight with the Katyanagi twins, when the camera pans up to see the hole in the roof, the audience gets a view of the moon with a hole in it as described in earlier exposition.
At the start of the film, most of the characters (and one location) are introduced with subtitles spelling out their name and briefly describing them.
Along similar lines, a sequence after Scott first talks to Ramona has subtitles describing the scene: "AND THEN. HE STALKED HER. UNTIL SHE. LEFT. THE PARTY."
The venue where Sex Bob-Omb battles Crash 'n' the Boyz is described as such: Fun Fact—This Place is a Toilet.
Another sequence has an on-screen inventory of most of the items in Scott and Wallace's apartment, and who they belong to (hint: bet Wallace).
Yet another transcribes word-by-word Stephen's nervous breakdown prior to playing at a Battle of the Bands, as the rival band's music drowns him out.
Various scenes have words appearing on-screen as chapter names (taken from the book), or respond to a character's dialogue, for example:
Stephen Stills: "'Amp vs. amp?' We'll be on stage at the same time?" Scott Pilgrim: "That's impossible!" Subtitle over next shot, showing two stages across from each other: Actually, no.
When Ramona first comments on Scott's shaggy hair, a series of subtitles explain that Scott's been cutting his own hair ever since Envy broke up with him, then goes on to explain the true circumstances surrounding their break up. Especially awesome because it uses the comic's art style.
After Todd hits Knives so hard her highlights came out of her hair, Envy coos to him:
Envy: You're incorrigible. Todd: I don't know the meaning of the word. SUBTITLE:HE REALLY DOESN'T.
The part where Stephen pees his pants when Gideon shows up to promote Sex Bob-Omb, and then an arrow appears on-screen pointing to his crotch with text reading, "PEE"?
To the director at least, a melanistic squirrel running through the background is one of the most consistently interesting parts of the movie.
Scott's desperate dive through the window of his apartment to evade Knives. Then reaching back in the window to grab his coat. Then walking down the sidewalk right behind her. All while Wallace is nonchalantly telling her she just missed him.
The amps during band practice at Stephen Stills' house are apparently of the "Lame Brand" company, with the logo emulating the Rock Band font. Once they move up to the Chaos Theatre, the amps are adorned "Sweet Brand".
While on the bus after the first evil ex fight, the street lights are shaped as X's behind Ramona, and like hearts behind Scott. After the shot where Scott understands that he and Ramona are actually dating, the street lights behind Ramona change into hearts as well.
After Gideon blows up, whilst Stephen Stills is scrabbling around to collect as much of Scott's winnings as he can, Neil simply bends down, picks up Gideon's gum, then puts it in his mouth. In fact, pretty much any time Neil is in the background is an example of this. Watch the movie once just to pay attention to him.
After Scott kills Todd the vegan police can be seen in the background giving each other a high five and shouting "Yeah!" triumphantly as they walk back to their Smart car in slow motion.
Plenty of sound-related gags. Many scenes have significant moments underscored by scene-relevant sound effects; for example, Sonic Boom's alarm goes off every time Envy is shown on-screen. Negascott whistles "We Are Sex Bob-Omb" after he walks out of frame.
When Scott's in the bathroom, part of the pee gauge can be seen in the mirror.
Genki Girl: Knives, who is almost always hyperactive and overexcited.
Genre Savvy: Scott displays this during his fight with Todd - Not only does he figure out that he could weaken Todd by getting him to consume non-vegan food & drink, but when he makes this move, he thinks very hard about putting the half & half milk into the cup he's holding to his chest after already putting soy into the cup he was offering Todd, to confuse Todd's telepathy and get him to fall for it.
Even earlier in that fight, he asks Ramona for the "CliffsNotes" on the guy in the hopes that some crucial detail in his backstory may be helpful.
Wallace too; when Matthew Patel comes crashing in, he's the one who yells for Scott to fight. By the time the second ex comes along, Wallace already has an attitude of Seen It All indifference (or he could just be sad that Scott has to defeat his "hetero crush").
Wallace: Scott. Evil Ex. Fight.
Genre Shift: Starts off a standard cute hipster comedy with Michael Cera... and then all of a sudden it becomes, well, Scott Pilgrim.
Giant Space Flea from Nowhere: Nega-Scott. It was thinly foreshadowed earlier in the movie when Scott faced the Nega-Ninja boss in the arcade game he was playing with Knives. There are several deleted scenes with Nega-Scott showing up in a mirror whenever Scott is being a particularly horrible person, which tends to shock him out of his asshole-ness. Edgar Wright says in the commentaries of these outtakes that they were cut because they distract too much from scenes that already have a lot up in the air.
Girl on Girl Is Hot: When Scott finds out that one of Ramona's exes was a woman, he refers to it as her "sexy phase". Though he's noticeably Squicked out when Ramona's about to explain just how she knows Roxy's weak point.
He's not squicked, he's just realized what Roxy's weakpoint means based on how Ramona started explaining it.
Good Adultery, Bad Adultery: Scott considers himself innocent when he cheats on Knives, yet he is "acutely aware" of when Envy/Natalie cheated on him over a year ago.
Green-Eyed Monster: The Yeti in the fight with the Twins is in part a manifestation of Scott's jealousy once he sees Ramona with Gideon at the show, more apparent when both it and his eye glows brightly green in Scott and the Yeti's split-screen close-up.
Guile Hero: Scott uses his wits to defeat both Lucas Lee and Todd.
Parodied: Ramona gives Scott a paper slip with her number within a second of his asking; Gideon pulls a pen and contract for Sex Bob-Omb out of nowhere; while off-screen for two whole seconds, Ramona apparently walks out of the club, creates a laminated list of her exes per Scott's request, and returns to hand it to him.
Hard Drinking Party Guy: Carries over from the books with Wallace. A perceptive viewer will note that he is almost always carrying a cup or glass of some kind, and presumably it's not coffee he's drinking.
Hilarious Outtakes: The film has such a high level of energy you can only imagine what filming the movie must have been like. As well, the aggressive editing and surreal nature of the film makes the outtakes seem like it belongs to a different movie altogether. As for something more traditional, Scott's "tossing the package into the garbage can behind him" took 33 tries.
