The superheros of "The Avengers" have taken the top prize at the MTV Movie Awards.
The action romp won three awards Sunday, including the top prize, movie of the year.
"What's the opposite of humbled? We're Biebered to be standing here," said "Avengers" writer-director Joss Whedon as he accepted the final golden popcorn trophy. "This is the award that means the most to me. I am so grateful and very excited for 2015; we're going to bring you 'Avengers 2.'"
"The Avengers" also won best fight and best villain for actor Tom Hiddleston.
Bradley Cooper and show host Rebel Wilson were each double winners at the ceremony at Sony Pictures Studios in Culver City, Calif. Cooper won the first prize of the night for his performance in "Silver Linings Playbook" and returned to the stage to accept best kiss honors for his smooch with co-star Jennifer Lawrence in that film.
"Thanks so much. Jen's not here. I'm sorry," he said to an audibly upset room about the absent actress. "I know. But, she was great to kiss."
Lawrence, who won the Oscar for her role in "Playbook," was also a double winner, though she wasn't on hand Sunday. In addition to the kiss award, she won the golden popcorn for her performance, but the prize wasn't presented on camera.
Wilson, who opened and closed the show wearing Iron Man-style armor, won breakthrough performance for her work in "Pitch Perfect" and shared in the film's award for best musical moment. Its stars, including Brittany Snow and Skylar Astin, opened the show with a mash-up medley.
"I was a bit surprised they asked me to host, and so was MTV -- they thought I was Adele," Wilson joked.
Other musical acts were Macklemore & Ryan Lewis and Selena Gomez, who debuted her new song, "Come and Get It," with a Bollywood-inspired performance.
Emma Watson received the Trailblazer Award. The "Harry Potter" star was honored for her film choices, which include "The Perks of Being a Wallflower" and the upcoming film "The Bling Ring."
"Becoming yourself is really hard and confusing and it's a process... but if you really put your heart in what you believe in, even if it makes you vulnerable, amazing things can and will happen," she told the audience.
Will Ferrell wore a three-piece suit covered in dollar bills to accept the Comedic Genius Award from "Game of Thrones" star Peter Dinklage.
"For those of you sitting here tonight who don't think I'm funny, I'll be happy to fight you in the parking lot after the show," said Ferrell, who is currently at work on "Anchorman 2," slated for release later this year.
The MTV Movie Awards are as much about the anticipated movies of the upcoming summer season as they are about the finest films of last year. Fans vote online for the winners in traditional and irreverent categories such as best fight, best kiss and best shirtless performance.
"Twilight" heartthrob Taylor Lautner won the shirtless award, which he jokingly accepted with a fake beer gut stuffed under his shirt.
The show also included unseen footage from next month's "Iron Man 3" and the world premiere of. Stars from other summer films -- including Chris Pine, Zoe Saldana and Zachary Quinto from the "Star Trek" sequel and Vin Diesel and Michelle Rodriguez from the "Fast & Furious" franchise -- appeared on stage during the ceremony.
Other presenters included Brad Pitt, Chris Rock, Adam Sandler, Seth Rogen, Zac Efron, Snoop Dogg/Lion and Kim Kardashian.
Hollywood has increasingly used the fan-driven MTV Movie Awards as a platform to promote its summer product. This year, the show was moved up from June to April to incorporate the entire blockbuster season, which begins in early May.
Jamie Foxx was a double winner, too. He shared the best WTF moment award with Samuel L. Jackson for their scenes together in "Django Unchained," and later thanked his daughter, parents and siblings in the audience as he accepted the Generation Award for his career in film.
