Superbad leads the nominees for the 2008 MTV Movie Awards, set to air live on June 1 from the Gibson Amphitheatre, with five nods, the network announced this morning. Juno is next with four nominations, followed by Enchanted, Transformers, Pirates of the Caribbean: At World’s End and Knocked Up, with three apiece.

Quipped MTV Networks Music, Logo and Films Group President Van Toffler: “As someone who had his nose rubbed up against a locker or two, it’s great to see my cinematic nerd brothers get their just rewards. It's our audience that has made these movies huge box-office hits, and they've clearly spoken by nominating films with strong characters they can all relate to.”

A new category—Best Summer Movie So Far— has been concocted for this year’s show in order to get the jump on the summer-blockbuster season. May 23 is the deadline for voting in the nine categories, as well as the user-generated Best Movie Spoof, on www.movieawards.mtv.com.

MTV has partnered with such video sites as Photobucket, MySpace, Daily Motion, Break, Buzznet, Heavy and FunnyorDie to give anyone with a creative vision a chance to submit their own original movie shorts parodying films from the past year. Finalists for the Best Movie Spoof will be flown to L.A. to attend the show, during which the winner will recive the award onstage.

Performers and presenters for the 17th edition of the show, hosted by Mike Myers, will be announced later.
