!![[Film/ScottPilgrimVsTheWorld The film]]:

* AcclaimedFlop: Despite it's niche appeal, the quirky story and humor went over extremely well with critics. ''Because'' of the niche appeal, however, it bombed at the box office and didn't recover it's budget until it was released on DVD.
* ActorAllusion:
** [[Creator/MaeWhitman Roxy]] not only uses a WhipSword, but [[WesternAnimation/AvatarTheLastAirbender wears fur-trimmed boots.]]
** Creator/BrandonRouth playing a [[Film/SupermanReturns frequently hovering super-powered badass with glowing eyes]]. [[spoiler:And is ultimately defeated by [[KryptoniteFactor the colour green]]]]
** This is the [[Film/{{Superbad}} second time]] that Creator/MichaelCera has accidentally [[ThanksForTheMammaries punched a girl in the boob]].
** [[Series/ArrestedDevelopment George Michael is fighting HER?]]
* BigNameFan: Creator/KevinSmith praised this film to the moon and back when it was released and borrowed heavily from it when he made ''Film/YogaHosers''.
* CaliforniaDoubling: Averted. The studio originally wanted the film to be shot in New York, Edgar Wright had to insist on using Toronto. One of the producers mentioned that normally, anything that identifies Toronto as Toronto has to be avoided when normally shooting a movie in Toronto, but here they could go nuts in shooting these locales. And they did: the movie features scenes at the (former) Honest Ed's thrift store and Casa Loma (specifically the bottom of its famous staircase, the Baldwin Steps, at the intersection of Davenport and Spadina), among others.
* TheCastShowOff
** Creator/EdgarWright deliberately choreographed the fight between Ramona and Roxie to show off Creator/MaryElizabethWinstead's gymnastic abilities and and Creator/MaeWhitman's dancing.
** Subverted with Michael Cera, who's an accomplished musician but had to learn how to play badly to be a more believable amateur.
* DawsonCasting: Knives Chau [[RunningGag (17 years old)]] is played in the film by Ellen Wong (25 years old around the time of filming). "Rated T for Teen" Stacey Pilgrim, 18 in the film, is played by Anna Kendrick (age 25 at the start of filming). Scott Pilgrim, by contrast, is 22 in the film, though Creator/MichaelCera was 20 at the beginning of filming, adding a bit of meta humor to the idea that Cera's character is dating someone significantly younger than him. Lampshaded by the 25 year old Wong:
--> '''Knives:''' He only likes her [Ramona] because she's really old! She's probably like 25!
* DevelopmentHell: Probably due to the fact that only the first book was released when the project was green lit. Edgar Wright was dead set on casting Michael Cera as Scott from the beginning but he was around 16 at the time. He was a much more reasonable 20 by the time filming commenced.
* DyeingForYourArt: Michael Cera underwent martial arts training for the film's fight scenes and enjoyed it so much he started training for real, making him a real life example of CrouchingMoronHiddenBadass: he still looks like a complete wimp, but now he's a complete wimp with a black belt.
* FakeAmerican:
** Matthew Patel is played in the film by British actor Satya Bhabha. [[JustifiedTrope Justified]] in that he moved from London to Chicago when he was 12 and is currently based in New York. Creator/EdgarWright originally didn't plan on casting British actors in his first American film, but was fooled by Bhabha's accent and had no idea he was born in the UK.
** Inverted with much of the rest of the cast, when you think about it, since many American actors play fake Canadians, mostly notably Kieran Culkin and Anna Kendrick
** Alison Pill, Creator/MichaelCera, and Ellen Wong are all actual Canadians. Pretty much everyone else are Americans pretending to be Canadians.
* NamesTheSame: Stephen Stills, named after the guitarist from Crosby, Stills, Nash & Young. He even hangs out with a guy named (Young) Neil.
* OrphanedReference:
** "Is that seriously the end of the story?" Originally, this was Kim's response to Scott's flashback about how he met Knives on the bus (she dropped her books, he picked them up), later echoed by Ramona when she hears it from Knives. The flashback scene was cut in the final version.
** In an early, discarded version of Scott and Ramona's first date, Ramona was seen lighting a cigarette, saying she smokes only on special occasions. Scott was supposed to be echoing her after his battle with Roxy, when he says he only drinks on special occasions.
* RomanceOnTheSet:
** Michael Cera (Scott) and Aubrey Plaza (Julie) started dating after meeting in this film.
** Anna Kendrick and Edgar Wright.
* ThrowItIn
** According to the DVD trivia track, Comeau's line of how "the comic is better than the movie" wasn't in the script, but Comeau's actor threw it in because Bryan Lee O'Malley was visiting the set that day.
** That light switch about ten feet up on the wall when Scott first talks to Ramona just happened to be in the house where the scene was filmed. The filmmakers made sure it get it in frame because it looked funny.
* WhatCouldHaveBeen:
** Reshoots in early 2010 were held partially to film the theatrical ending. Originally, Scott and [[spoiler:Knives]] ended up together. The ending screened to test audiences and will appear on the DVD.
** [[http://theplaylist.blogspot.com/2010/08/scott-pilgrim-ending-that-was-never.html An idea for the same reshoots, which was never filmed due to time constraints]], involved the film turning out to be AllJustADream -- and that [[spoiler:Scott is actually a serial killer who murdered seven people]]. It is implied this ending would only appear on the DVD as an extra. Fans of this concept also whipped together [[http://www.half-assed.com/strips/39.html a little tribute to it]].
** The DVD contains storyboards and concept art for a very different conclusion to the final battle. Two words: [[spoiler:Mecha Gideon]].
** At one point in development, Envy Adams was considered to be Ramona's fourth ex, [[CompositeCharacter combining her character with with Roxie Richter]]. In the final film, the two remained separate characters (as a possible artifact of this concept, Roxie is defeated the same way Envy is in the comics).
** Roxie's line "Shut the [dial tone] up!" was originally going to be uncensored, abiding to the MPAA's "one f-bomb" rule for PG-13 movies. However, because Scott already had the line "You cocky cock!" it would have gotten the movie an R. Thankfully, [[TropesAreNotBad the resulting joke is much funnier]].
* WordOfGod: Creator/EdgarWright claims that the battle scenes are meant to feel like musical numbers, in that they only occur when the characters' emotions are too extreme for dialogue.
* WordOfSaintPaul: 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:
** Creator/MaryElizabethWinstead has revealed that [[spoiler:Ramona's little brother died when she was younger, and she wears one of his shoelaces as a necklace in memory of him]].
** Creator/AubreyPlaza mentioned in numerous places that Julie Powers had an [[spoiler:unrequited crush on Scott]] in college, (one that [[http://www.avclub.com/articles/aubrey-plaza,44276/ possibly continues into the present]],) which is why she's so hostile to him (especially if, like in the books, [[spoiler:Scott's eventual girlfriend, Envy, was Julie's roommate]]). [[WordOfGod Bryan Lee O'Malley]] contests this as Plaza [[http://scottpilgrim.ning.com/forum/topics/10-secret-things-for-each?id=972072%3ATopic%3A167793&page=1#comments "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 [[spoiler: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)[[/note]]
