If you wanted to be nominated for Best Male Performance at this year's MTV Movie Awards, it was all about embracing your inner action hero — unless you're Zac Efron.

With four of the men — Christian Bale ("The Dark Knight"), Robert Downey Jr. ("Iron Man"), Shia LaBeouf ("Eagle Eye") and Vin Diesel ( "Fast & Furious") — nominated for action flicks, Efron stands alone, thanks to reprising his role as Troy Bolton in "High School Musical 3: Senior Year."

With Efron as the song-and-dance man in a sea of testosterone-fueled dudes, it looks like it could be an epic battle that only the most genius comic book writer could come up with: Iron Man vs. Batman. Downey and Bale managed to have blockbuster summers last year with "Iron Man" and "The Dark Knight," so it's just a matter of who the fanboys vote for. And don't count out Diesel in this category: "Fast & Furious" was a huge movie as well and could possibly spoil it for the superheroes.

LaBeouf might have had an "Eagle Eye" in his nominated role, but it will still be hard for him to best Efron and his rabid tween fanbase. Efron told us he loved dancing in "HSM 3," since it allowed him to live out a childhood dream.

"When we got to the junkyard, everything just opened up for us," he explained about his "The Boys Are Back" dance sequence. "We had all these props and cars. It was like a dream come true. I've wanted to do that since I was, like, 5."

Will the vampires grab more trophies than the slumdog? What was the year's ultimate onscreen WTF moment? It's up to you to decide the winners of the 2009 MTV Movie Awards. Vote now, and tune in on Sunday at 9 p.m. ET, when the big show airs live from the Gibson Amphitheatre in Universal City, California.
