The buzz surrounding Edgar Wright's "Scott Pilgrim vs. the World" continues to build in anticipation of the graphic novel-turned-feature film's release this week. In addition to welcoming the entire cast to our Comic-Con live stream last month, MTV News was lucky enough to spend a day on the high-energy set in Toronto last year.

The day we visited, Mary Elizabeth Winstead (Ramona Flowers) informed us that Wright and company were getting ready to shoot a complex fight/concert sequence involving Ramona's Evil Ex # 3, Todd Ingram, and Pilgrim's ex-turned-rock star Envy Adams.

Brandon Routh described Ingram as "basically the best ex," boldly telling us that the fight between his character and Pilgrim (Michael Cera) was not going to end well for the film's namesake. "Scott's going to get the crap beat out of him by me pummeling through walls and everything," Routh said. "And then we have a big bass battle, which is a lot of fun."

"This set is based on a real rock club, Lee's Palace," Wright explained. "And the only reason we're shooting [on a] set is because a whole bunch of walls need to get knocked down."

"We're kind of in the middle of our battle of the bands," Mark Webber (Sex Bob-omb bandmember Stephen Stills) said of his character's action in the scene. "We're getting ready to see the Clash at Demonhead perform."

Speaking of Demonhead, the band's lead singer, Envy Adams (Brie Larson), said that they're going to rock — literally and figuratively. "The main thing is that we want to spread the love and play a really rockin' show, and hopefully something really kind of universal happens tonight."

Judging from the reactions from the extras in the concert sequence, Clash at Demonhead did indeed play a rockin' show that day. Winstead said that the music and overall energy from the extras made the scene.

"The music is amazing, and the extras have been really amazing in making it seem really authentic and real," she said. "It's been an awesome day, because it feels like we're just hanging out at a really fun concert."
