'Twilight' Vs. 'Harry Potter': Who Will Win First 2011 MTV Movie Award?

Plus: Jason Sudeikis goes inside nominated movies, Steven Spielberg presents a 'Super 8' exclusive and more Act 1 inside scoop!

In the last couple days leading up to the 2011 MTV Movie Awards, we've been all about bringing fans as close to the awards-show action as possible.

The intrepid MTV News team working from the show's site in Universal City, California, has been privy to countless exclusive sneak peeks, like advance screenings of "Horrible Bosses," "The Help" and more during our Sneak Peek Week; the promise of an awesome "Harry Potter and the Deathly Hallows, Part 2" exclusive during the big show; and the very first look at "The Twilight Saga: Breaking Dawn - Part 1."

If that isn't enough to get you to tune in Sunday, MTV News' Jim Cantiello tracked down the show's supervising producer, Jane Mun, to get inside info about what viewers can expect to see during the first act of the show.

"In Act 1, we have Jason Sudeikis, our host, going in and out of our movies, but I can't tell you what [exactly] that is, because that's a surprise that we have to keep," Mun teased. "You'll notice right here a name [Taylor Lautner] on this board," she added, gesturing to a large poster board covered in different-colored pieces of paper, each with names of people and events that will occur during the telecast.

"I can't spill the deets," Mun said when pressed about what the "Twilight" superstar will be doing onstage. Cantiello suggested that whatever Lautner does, it should be shirtless -- which Mun didn't confirm or deny.

"Then we have Jason come out and greet the room and our viewers to a really awesome monologue, " Mun continued, adding that she's alerted her censor team that they might have some extra work during Sudeikis' opener.

"I've already talked to the censors, and they are in for a treat," she said with a smile.

The first award of the night will be Best Male Performance, which pits supernatural studs Robert Pattinson and Taylor Lautner ("The Twilight Saga: Eclipse") against each other and "Harry Potter and the Deathly Hallows, Part 1" star Daniel Radcliffe, Jesse Eisenberg ("The Social Network") and Zac Efron ("Charlie St. Cloud"). Who will come out on top?

"Then, we just announced [Thursday] morning, is going to be the exclusive sneak peek of 'Super 8,' " with director J.J. Abrams and producer Steven Spielberg and stars Elle Fanning and Joel Courtney presenting. "And that is our Act 1!"
