Ever since the first caveman hit the second caveman over the head with a Brontosaurus bone, mankind has been fascinated by a fight. Man vs. man, woman vs. woman, whether it's over a spurned lover, stolen property or a simple "yo' mama" joke, few things are more exciting to watch — and once again, the MTV Movie Awards is here to recognize the most memorable brawls and battles of the past year.

Chances are you've never personally witnessed a battle between a demon and a supernatural prince; a pair of impossibly handsome vampires; a caped crusader and an anarchic clown; or two bridezillas brawling in the aisle. OK — if you went to college, you've probably seen three stoners trashing an apartment.

Be sure to head on over to the Best Fight voting page, where all of the above are currently embroiled in the final days of an even greater battle. The winners will take home the big trophy Sunday evening at 9 p.m. ET — but first, at the risk of angering some obviously hot-tempered talents, we handicap the competition:

Who's the Favorite?

If there's one thing the entertainment industry has learned in the past year, it's that you should never underestimate the power of the Twilighters. The big-screen adaptation of Stephenie Meyer's beloved novel surprised prognosticators last November by opening to record-breaking numbers, and the mere thought of Robert Pattinson and Cam Gigandet accepting an award onstage seems like enough to get thousands of teenage fingers clicking on that "vote" button. OME, indeed.

Who's the Underdog?

Can a movie that earns $500 million and eight Oscar nominations ever truly be an underdog? That might be the case with "The Dark Knight," whose fan- and critic-beloved splendor may have finally met its match in Robert Pattinson's carefully coiffured hair. Nevertheless, Joker vs. Batman was one of the highest moments in film from 2008, and if a fraction of those "Dark Knight" fans cast their vote, the Twilighters could be in more trouble than Waylon Forge on his boat.

Inside Scoop

» During the wedding-shower scene in "Bride Wars," many of the extras in the background are wives and girlfriends of current players for the Boston Red Sox. The movie was filmed largely in the Boston area.

» When Seth Rogen originally wrote "Pineapple Express," he had planned to play the role that eventually went to James Franco. It was a similar bit of serendipity to "Superbad," which he had written with the intention of playing the Jonah Hill role.

» The character of Hellboy's real name is Anung Un Rama, which means "the Beast of the Apocalypse."

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 May 31 at 9 p.m. ET, when the big show airs live from the Gibson Amphitheatre in Universal City, California.
