Titled Scott Pilgrim vs. The Animation, the cartoon will be shown at midnight on August 12 to promote the comic's movie adaptation.
According to SlashFilm, the shorts are based on outtakes from Edgar Wright's Scott Pilgrim vs. The World. Michael Cera and Allison Pill will reprise their roles from the film while Mae Whitman and Jason Schwartzman will voice different characters.
"We were approached by Universal to do something cool around the release of Scott Pilgrim vs. The World," said producer Jason DeMarco.
"Being huge fans of the comic, and very excited about the film, we asked if we could produce an animated short in the style of the comic. The filmmakers and Bryan Lee O'Malley were into the idea, so we actually made it."
Scott Pilgrim vs. The World arrives in theatres on August 13.
