Random Trivia For This Title:
- Anna Kendrick, as the character Stacey Pilgrim, wears the actual name badge of the real-life Stacey, on whom the comic creator, Bryan Lee O'Malley, based the character. (In one of the DVD commentaries, Kendrick specifically asks that someone add this trivia to IMDb.)
- Edgar Wright told his casting director not to hire any English actors as this was his first North American film. Satya Bhabha, who played Matthew Patel, successfully passed the audition with a non-English accent. Bhabha later revealed he was from London, England.
- When Scott opens the door to receive his package, Michael Cera actually did throw the package over his shoulder into the bin after nearly 40 takes (most of which are seen on the "outtakes" of the DVD). However, the signature shown on-screen was a visual effect superimposed onto the paper.
- Edgar Wright obtained permission to use the famous theme song from the SNES game, The Legend of Zelda: A Link to the Past, by writing a letter to Nintendo, saying that it is considered to be "the nursery rhyme of this generation". He was also allowed to use the [Seinfeld] theme song for a sitcom-style sequence.
- The four cast members that made up the band "Sex Bob-Omb" spent several weeks learning how to play together as a band. Mark Webber, Alison Pill and Johnny Simmons all had to learn their instruments from scratch, while Michael Cera had to "dumb down" his bass playing in order to not outshine his band mates.
- Mary Elizabeth Winstead actually memorized ALL of the kinds of tea that her character rambles. Some crew members kept offering for her to just read it from a piece of paper, but she insisted on learning it all.
- Edgar Wright has stated the movie was done in the style of a Musical, but instead of the characters breaking into song and dance, they break into a fight. The battle between Scott Pilgrim and Matthew Patel is done in the style of a Bollywood fight scene.
- Whenever the moon is shown, it is full and there is a hole in it. Ramona's third boyfriend, Todd Ingram, is mentioned in flashback to have punched the hole there for her when they dated. In the graphic novel, Todd punches a second hole in the moon for Envy Adams.
- When Ramona asks Scott how old Knives is, the roulette wheel in his mind has the following choices: "She's Nobody", "She's Forty!", "Idiot!", "No Speaka English", "When's Dinner", "Uhh...", "Tell Pac Man Story", "No, You Are", "Pass Out", "It Was Nothing", "Who Her?" and "I Gotta Pee". Interestingly, in the film Scott Pilgrim is 22 years old and his sister, Stacey Pilgrim, is 18. In real life actor Michael Cera is nearly 3 years younger than actress Anna Kendrick. Likewise, Ellen Wong, who plays 17 year old Knives Chau, is actually 3 years older than Cera.
- The original concept for "Scott Pilgrim" is based around 2 premises. The first was the idea of "What if, after a life of playing fighting games, someone confronted you and you actually had the ability to fight like a "Street Fighter" character?" The second concept came about when Bryan Lee O'Malley was dating his future wife, [?] Hope Larson. When he learned that she had dated three different guys named Matthew, O'Malley came up with the idea of a League of Matthews. This idea developed into the League of Evil Exes. Matthew Patel is the only Evil Ex to keep the name Matthew.
- At the party where he talks to Ramona for the first time, Scott holds up a very badly drawn picture of Ramona and asks if anyone has seen her. Director Edgar Wright said Scott was originally supposed to hold up a picture of Ramona from the comic book series, but felt the silly drawing Scott holds up was more comedic.
- To avoid an R-Rating, the word "F}$", said by Envy to Julie, had to be bleeped out because Scott Pilgrim calls Todd Ingram a "cocky-cock" earlier in the film.
- One of the evil exes is portrayed by Mae Whitman who previously performed as the girlfriend of Michael Cera's character in [Arrested Development].
- The 8-bit Universal logo at the beginning of the film was Edgar Wright's idea; it was then designed by his brother Oscar Wright, the concept designer and storyboard artist on the film. The logo seen in the final film was actually only a first-draft. It was not yet considered finished when test screenings began, but audiences reacted so positively to it that it was decided that no further work need be done.
- The stunt doubles of Lucas Lee are the actual stunt doubles for actor Chris Evans. Only a quarter of the doubles resemble Evans.
- Kim Pine becomes visibly upset when she finds out that the rival band "Crash and the Boys" has a girl drummer. All drummers in the movie are girls.
- The film cast includes one Oscar winner, Brie Larson, and one Oscar nominee, Anna Kendrick.
- Mathew Patel is the only Evil Ex that Scott defeats on his own. Lucas Lee kills himself, the Vegan Police helps to defeat Todd, Ramona helps to defeat Roxie, Stephen Stills and Kim help to defeat the Katayanagi Twins, and Knives helps to defeat Gideon.
- After Scott dies in the first fight against Gideon, an arrow appears and points to Scott with the word "dead" written above it. Bryan Lee O'Malley saw this shot and was inspired to put it in the (then) unwritten final book of the Scott Pilgrim series, "Scott Pilgrim's Finest Hour".
