Earth's Mightiest Heroes have snagged a few nominations at the 2013 MTV Movie Awards, and Best On-Screen Duo is a well-deserved one. While "Marvel's the Avengers" focused mainly on the best super-sextet in film history, there was one duo that managed to stand out. In the midst of an alien invasion and the clashing of worlds, Iron Man and the Hulk's relationship gave the film a solid, relatable backbone that made even the most skeptical moviegoers stand up and cheer. You can catch Downey Jr. and Ruffalo in action below, and be sure to check out all the other nominees.
