Scott Pilgrim vs. the World is a 2010 comedy film directed by Edgar Wright, based on the graphic novel series Scott Pilgrim by Bryan Lee O'Malley. The film is about Scott Pilgrim (Michael Cera), a young Canadian musician, meeting the girl of his dreams, Ramona Flowers (Mary Elizabeth Winstead), an American delivery girl. In order to win Ramona, Scott learns that he must defeat Ramona's "seven evil exes", who are coming to kill him.

Scott Pilgrim vs. the World was planned as a film after the first volume of the comic was released. Wright became attached to the project and filming began in March 2009 in Toronto. Scott Pilgrim vs. the World premiered after a panel discussion at the San Diego Comic-Con International on July 22, 2010. It received a wide release in North America on August 13, 2010 in 2,818 theaters. The film finished fifth on its first weekend of release with a total of $10.5 million. The film received generally positive reviews by critics and fans of the graphic novel, but it failed to recoup its production budget during its release in theaters, grossing $31.5 million in North America and $16 million overseas. However, the film has fared better on home video, becoming the top-selling Blu-ray on Amazon.com during the first day it was available and has since gained a cult following.

Scott Pilgrim is a series of graphic stories by Bryan Lee O'Malley. It consists of six digest size black-and-white volumes, released between August 2004 and July 2010, by Portland-based independent comic book publisher Oni Press. It was later republished by Fourth Estate, an imprint of HarperCollins. The series is about 23-year-old Canadian Scott Pilgrim, a slacker and part-time musician who lives in Toronto and plays bass guitar in the band Sex Bob-Omb. He falls in love with American delivery girl Ramona Flowers, but must defeat her seven evil exes in order to date her.

A film adaptation of the series titled Scott Pilgrim vs. the World starring actor Michael Cera in the title role was released in August 2010. A videogame of the same name developed by Ubisoft for PlayStation Network and Xbox Live Arcade was released the same month.

Creator Bryan Lee O'Malley was inspired to create the series and eponymous character of Scott Pilgrim after listening to Canadian band Plumtree's 1998 single "Scott Pilgrim", a song then-Plumtree singer Carla Gillis describes as "positive, but...also bitter sweet." In particular, O'Malley was inspired by the lyric "I’ve liked you for a thousand years,".

A pilgrim (from the Latin peregrinus) is a traveler (literally one who has come from afar) who is on a journey to a holy place. Typically, this is a physical journeying (often on foot) to some place of special significance to the adherent of a particular religious belief system. In the spiritual literature of Christianity, the concept of pilgrim and pilgrimage may refer to the experience of life in the world (considered as a period of exile) or to the inner path of the spiritual aspirant from a state of wretchedness to a state of beatitude.

Pilgrims and the making of pilgrimages are common in many religions, including the faiths in ancient Egypt, Persia in the Mithraic period, India, China, and Japan. The Greek and Roman customs of consulting the gods at local oracles, such as those at Dodona or Delphi, both in Greece, are widely known. In Greece, pilgrimages could either be personal or state-sponsored.

In the early period of Hebrew history, pilgrims traveled to Shiloh, Dan, Bethel, and eventually Jerusalem, see also Three Pilgrimage Festivals, a practice followed by other Abrahamic religions. While many religious pilgrims travel toward a specific destination, a physical location is not a necessity. One group of pilgrims in early Celtic Christianity were the Peregrinari Pro Christ, (Pilgrims for Christ), or "white martyrs". They left their homes to wander in the world. This sort of pilgrimage was an ascetic religious practice, as the pilgrim left the security of home and the clan for an unknown destination, in complete trust of Divine Providence. These travels often resulted in the founding of new abbeys and spreading Christianity among the pagan population in Britain as well as in continental Europe.
