It's the big enchilada, the supreme dream, the prize on which the entire movie-loving world will be focusing its eyes: Best Movie at the MTV Movie Awards. Past winners have included such instant classics as "Pulp Fiction," "Titanic," "Gladiator" and all three "Lord of the Rings" movies. But which film will close out tonight's live ceremony by joining their hallowed ranks?

This year's contest promises to be tighter than Zac Efron's pants. We have the dueling superheroes of "Iron Man" and "The Dark Knight," Oscar winner "Slumdog Millionaire," the final installment of the beloved "High School Musical" franchise and arguably the most significant film of the year for teenagers: "Twilight."

In any given year, there can be a lot of great films — but only one Best Movie. So let's take a look at our picks to feast heartily on tonight's Golden Popcorn. (But remember, voting for Best Movie is open throughout the show, so it's still anyone's game.)

Who Is the Favorite?

It's no secret that all of us here at MTV — especially yours truly — will always have a special place in our hearts for "Twilight." It's the little movie that could: Despite having a low budget, being rejected by virtually every studio, being hated by fanboys and featuring little-known actors in all its roles, it was boosted up by a fiercely loyal fanbase to become the sweetest cinematic surprise of the past year. MTV was the first media outlet to report regularly on the phenomenon. Having seen the "New Moon" trailer we're debuting during Sunday night's show, I can safely say that the Cullen family is here to stay. Some people may be Team Edward, and others may be Team Jacob, but one thing is certain: There are a whole lot of people out there who are Team "Twilight."

Who Is the Underdog?

Even the most die-hard Twilighter has to admit: "Dark Knight" was the most universally embraced film of last year. Somehow, Christopher Nolan, Christian Bale, Heath Ledger and company perfected a formula that delighted geeks and girls, parents and teens, critics and popcorn-munchers alike. Undoubtedly, Batman deserves to fly high once again — as long as the equally beloved "Iron Man" doesn't split his vote and prove to be as deadly an adversary as The Joker himself.

Inside Scoop

» Based on the exchange rate when "Slumdog Millionaire" was released, Jamal hardly would've become a millionaire here in the United States. The 20,000,000-rupee grand prize on India's "Who Wants to Be a Millionaire" would be worth roughly $411,600 in U.S. money.

» For several years, "Iron Man" kicked around Hollywood with such actors as Tom Cruise attached to play Tony Stark. For a lengthy period of time, the film was to be directed by "The Notebook" filmmaker Nick Cassavetes.
