After reading his post I spent all day thinking about this idea. My God that would have been SUCH a good marketing campaign.
Patel could have been a faux fashion commercial about pirates being in this season. Like a fake GAP ad or something, with him and some hipster [demon] chicks posing and a voice-over talking about their looks, and then at the end, "And I'm coming for YOU, SCOTT PILGRIM!"
Lucas Lee, the fake movie trailer, with him pausing in the middle of an action scene and turning towards the viewer, saying the same thing.
Todd could be an pro-vegan ad, or an ad for soy milk, and at the end he's listing the benefits of being vegan and he could say, "Plus, awesome powers to kick your face in, Scott Pilgrim."
Roxie's could have been set up like an ad for a school, but it's a ninja school, and at the end she turns towards the camera, "You won't even know what hit you, SCOTT PILGRIM!"
The Twins would obviously be a fax CD commercial, with them talking about the Battle of the Bands contest coming up, "See you there, SCOTT PILGRIM!"
Gideon's would just be a super sexy ad for the Chaos Theater opening soon with a female announcer's voice, and the end of the ad would just be "See you opening night, Scott Pilgrim."
Fuck, that would have driven up INSANE word of mouth for this movie. People would be like "Who is Scott Pilgrim? Why are these people after him?" What did he do? Uuuughhhh so depressing!!
