The power of the Golden Popcorn is once again yours! Starting today, we're asking you to cast your votes and select the nominees for the 2011 MTV Movie Awards in 13 categories ranging from the familiar (Best Movie, Best Kiss) to the brand-new (Best Line from a Movie).

Can "Eclipse" reprise the success of "Twilight" (seven nods) and "New Moon" (five nods) before it? Will Biggest Badass star go to Robert Downey Jr.'s sardonic, super-suited hero in "Iron Man 2," to Angelina Jolie for her acrobatic brawling in "Salt," or someone else entirely? Which star's unforgettable line — Liam Neeson's plea to release the Kraken? Justin Timberlake's insistence that only a billion dollars is truly cool? — will be the first to take home this award? For a third-straight year, it's up to you!

Here's how it'll work: Starting Tuesday (March 22) and running through April 5, you can log onto MovieAwards.MTV.com to nominate your favorite movies, stars and crazy cinematic moments. Once the final nominees are announced, head back to the site to vote for the winners from May 3 through June 4. Voting for Best Movie, however, will remain open throughout the live ceremony on June 5 — meaning you'll have a chance to affect the night's biggest prize until the very last minute.

"MTV's viewers are die-hard film buffs, and we love to see how they wield that dedication when voting for the MTV Movie Awards," said Stephen Friedman, general manager of MTV. "This year's show will once again reward movie buffs with previews of the year's most anticipated movies and one-of-a-kind moments that become pop-culture history."

The 20th Annual MTV Movie Awards will air live on Sunday, June 5, at 9 p.m. ET from the Gibson Amphitheatre in Universal City, California.
