Will Jennifer Lawrence, Bradley Cooper Dance Away With MTV Movie Award?

This Sunday at 9 p.m. ET, the best big-screen buddies face off for a chance at Best On-Screen Duo.

We are just barreling down the road to the 2013 MTV Movie Awards, but we're taking a few stops along the way to check out the contenders in each category.

In the On-Screen Duo category, the year's best cinematic pairs will be battling it out for your votes and Movie Awards supremacy. It all goes down this Sunday, April 14 at 9 p.m. ET on MTV.

Robert Downey Jr. and Mark Ruffalo in "Marvel's The Avengers"

You know what makes the friendship of Bruce Banner and Tony Stark so cool? One word: science. The brainiac buds of "Marvel's The Avengers" stole their show in their own, individual ways, but when they came together for Joss Whedon's superhero team-up movie, that's when the magic really happened. It was fitting that one of the final images leaves us with Bruce and Tony driving off together, presumably to do some sweet science stuff. We can only imagine.

Will Ferrell and Zach Galifianakis in "The Campaign"

"The Campaign" had us torn. Who do you vote for when your choice is between Zach Galifianakis, the man whose "Between Two Ferns" puts any real talk show to shame, and Will Ferrell, this year's MTV Comedic Genius? Thankfully, we had an entire movie to watch the two funnymen spar it out in a no-holds-barred chuckle fest where everyone wins.

Leonardo DiCaprio and Samuel L. Jackson in "Django Unchained"

The tricky thing about this pair of villains from Quentin Tarantino's epic southern is that you think you've got them figured out as soon as you meet them. DiCpario is Calvin Candie, the cruel plantation owner, and Jackson is Stephen, the slave that gamed the system. But as we get to know both, their dynamic shifts in a frightening, brilliant, and purely Tarantinian way.

Bradley Cooper and Jennifer Lawrence in "Silver Linings Playbook"

Perhaps the best way to test an onscreen duo's compatibility is to enter them in a ballroom dancing competition. Well, if that was the only test of a true pair, Pat and Tiffany from "Silver Linings Playbook" might not do so well, but they'd definitely give it their all. The romantic pair beat each other's crazy and completely melted our hearts in the process.

Mark Wahlberg and Seth MacFarlane in "Ted"

Only one of the pairs nominated for On-Screen Duo this year had to be content with the fact that one half was a computer-animated teddy bear. For "Ted," Seth MacFarlane and Mark Wahlberg made us believe that not only was the foul-mouthed bear real, he had a real best friend in John. The duo had us laughing, crying, and wondering when the last time we watched "Flash Gordon" was.
