Watch: New 'Scott Pilgrim vs. The World' trailer explodes on Facebook

In a Memorial Day surprise, Universal Pictures debuted the new trailer for "Scott Pilgrim vs. the World" on the film's official Facebook page today. "Pigrilm" is one of the few non-franchise films to create some legitimate buzz this summer and after the worst Memorial Day weekend box office in 17 years, Hollywood could use it.

Directed by Edgar Wright ("Hot Fuzz," "Shaun of the Dead") and based on the graphic novels by Bryan Lee O'Malley, "Scott Pilgrim" follows the story of the title character (played by Michael Cera) who falls for the mysterious Romana Flowers (Mary Elizabeth Winstead) only to discover he must defeat her seven evil ex-boyfriends to secure her love.  It seems the "Pilgrim" world is one were everyday people have powers you'd expect to see in video games.  The trailer does a great job of selling that concept by having Pilgrim grab a "life" out of thin air

The preview also gives us our first real look at Pilgrim's gay roommate Wallace Wells (Kieran Culkin who somehow doesn't appear as cute as he should), evil ex-boyriend Gideon Gordon Graves (Jason Schwartzman), eternally moody bandmate Kim Pine (Alison Pill) and a quick glimpse at groupie Knives Chau (Ellen Wong).

The biggest question mark about "Pilgrim" has been whether Cera would be able to convey the youthful enthusiasm of the character which is a bit closer to rejected, geeky frat boy than the dry sense of humor the "Superbad" star is known for.  And, considering Cera's theatrical returns lately, he could use a hit with "Pilgrim." Thankfully, the more footage fans see, the more he's slipping (somewhat) comfortably into the role.

You can watch the new preview on Facebook or, because we just couldn't help ourselves, check it out embedded on this page.  And, as always, don't be shy. Tell us what you think.

"Scott Pilgrim vs. The World" opens nationwide on August 13.
