Since film fans made "The Twilight Saga: Eclipse" the most nominated film leading into the 2011 MTV Movie Awards, we had to return the favor with some "Twilight" goodies during the big show.

"Twilight" leading lady Kristen Stewart and her main men, Robert Pattinson and Taylor Lautner, will be presenting an exclusive trailer from the saga's highly anticipated fourth film, "The Twilight Saga: Breaking Dawn - Part 1," during the awards show, airing Sunday live at 9 p.m. ET/PT on MTV.

For the die-hard "Twilight" fans who've been following all the news about "Breaking Dawn - Part 1" — for which we compiled this handy guide — the exclusive trailer premiering during the Movie Awards will be the very first video from the film. Up until now, we've had to make do with production photos, teaser art and posters.

MTV News recently caught up with Elizabeth Reaser, who plays Cullen matriarch Esme, to get her take on filming the two-part "Twilight" finale. "There was a lot of emotion," she said during an MTV Sneak Peek Week screening of her latest movie, "The Art of Getting By." "I mean, [for] months we had been through so much different weather craziness [in all different locations that] we were in denial of it the whole time."

She recalled saying goodbye to the epic five-movie saga while shooting the highly anticipated Edward/Bella wedding scene, even though her work on the film wasn't quite over; she had to stick around a bit longer to finish up some shooting on the film. "Suddenly, we were on the dance floor at the wedding, and it was suddenly over," she said. "It's also 7 in the morning, and we had been shooting all night, so it was this weird, surreal experience. We were all in shock."

Stewart, Pattinson and Lautner will be in good company, when they grace the MTV stage. They join previously announced presenters and attendees, including Nicki Minaj, Rosie Huntington-Whiteley, Selena Gomez, Emma Stone, Cameron Diaz, Leighton Meester, Katie Cassidy, Shia LaBeouf, Ryan Reynolds and Josh Duhamel.

"Eclipse" leads the pack of 2011 MTV Movie Awards nominees with eight nods, including Best Movie, Best Fight and Best Kiss. "Inception" snagged the second-most nominations (seven), followed by "Harry Potter and the Deathly Hallows, Part 1," which received six nods.
