The cast of “The Hangover” shouldn’t bother guzzling too much Champagne to celebrate leading with the most MTV Movie Award nominations (six). “Twilight: New Moon” may have merely earned five, but that’s exactly how many MTV trophies the original “Twilight” claimed last year. Clearly, voters love blood guzzlers.

Last year at the MTV Movie Awards, ”Twilight” won best film, best fight (Cam Gigandet, Robert Pattinson), kiss (Kristen Stewart, Pattinson), female performance (Stewart) and breakthrough male performance (Pattinson). It suffered only two defeats. Taylor Lautner lost best breakthrough male (to costar Pattinson — only one could win the category) and best song (“Decode” lost to “The Climb” from “Hannah Montana: The Movie”).

Just because “Twilight” won best film last year doesn’t mean “New Moon” is ill-starred. All three installments of “Lord of the Rings” won the same crown from 2002 to 2004.

But the romp by “Rings” does suggest that a movie other than “The Hangover” might have a shot at besting “Twilight: New Moon.” That’s “Avatar, which, just like “Rings,” was a fantasy blockbuster that broke box-office records. Or, rather, “Avatar” is sci-fi, that is, a genre voters preferred when picking past best films “Transformers” and “The Matrix.”

Because winners are decided by Web-based votes, that sets up a fierce cyber war between “Twilight” and “Avatar” fanatics. Everybody, duck!
