‘Avengers: Age of Ultron’ Clip: Watch Iron Man and Hulk Fight

The Avengers will not only have to worry about fighting enemies in the upcoming "Avengers: Age of Ultron," they will also have to duke it out with each other.

In a new clip, released during the 2015 MTV Movie Awards on Sunday, fans got a sneak peak into an epic battle between Iron Man, played by Robert Downy Jr. and the Hulk, played by Mark Ruffalo. In the nearly 90-second clip, the Hulk appears to be under a spell cast by Scarlet Witch (Elizabeth Olsen).

Watch the clip here:

Right before the clip debuted, Downey Jr. accepted the Generation Award, which was jointly presented by his "Avengers" co-stars, Chris Evans, Chris Hemsworth, Ruffalo, Jeremy Renner and Scarlett Johansson.

In his speech, the 50-year-old actor jokingly said, "When the first generation award was given in 2005, I thought simply, 'Where's mind?' And I've spent 10 long years patiently awaiting...to receive the recognition I've so deserved."

Downey Jr. then got more serious and continued, "In the 34 years that have passed since the birth of MTV, I've grown up, I've struggled, I've failed. I've partied way too much. I begged for second chances and literally clawed my way to the top."

Before ending his speech, he asked his co-stars to "take a knee," which they all did gracefully.

"I try to live honorably and never forget my love of the game and my friends...if a man is judged by the company he keeps, I must be doing something right."

"The Avengers: Age of Ultron" hits the theaters on May 1, 2015.
