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

* AcclaimedFlop: Was praised by many a critic for its original premise and overall fun story (even if most of the jokes was aimed at younger demographic). But did horribly at the box office, coming in fifth when it was released and failing to recoup its budget until the DVD came out.
* ActorAllusion: [[MaeWhitman Roxy]] not only uses a WhipSword, but [[WesternAnimation/AvatarTheLastAirbender wears fur-trimmed boots.]]
** Brandon Routh playing a [[SupermanReturns frequently hovering super-powered badass with glowing eyes]]. [[spoiler:And is ultimately defeated by [[KryptoniteFactor the colour green]]]]
** This is the [[{{Superbad}} second time]] that Michael Cera has accidentally [[ThanksForTheMammaries punched a girl in the boob]].
** [[Series/ArrestedDevelopment George Michael is fighting HER?]]
* 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. 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.
* 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. Director Edgar Wright 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, Michael Cera, 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.
* 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.
* 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]]
* WordOfSaintPaul: In commentary, Aubrey Plaza, who plays Julie, asserted that her character had (and possibly has) an unrequited crush on Scott, which is why she's so hostile to him. While Bryan Lee O'Malley, the creator of the original ''ComicBook/ScottPilgrim'' comics, responded that Plaza was "making shit up", Edgar Wright, the director of the film adaptation, supported this view.

!!!Random facts
* An odd fact mentioned in the making-of documentary. 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.
* Ellen Wong, the actress who plays Knives, is actually a few years older than Michael Cera.
* This movie has caused Michael Cera to turn himself into a real life example of CrouchingMoronHiddenBadass. He underwent martial arts training for the film's fight scenes and enjoyed it so much he started training for real. He still looks like a complete wimp, but nowadays he's a complete wimp with a black belt.
