MTV debuted an extended look at a fight between Iron Man and Incredible Hulk from the upcoming Avengers: Age of Ultron and ... yeah. It's pretty hardcore. Take a look.
So there is a pretty major spoiler in here: We now know that this battle happens due to the Scarlet Witch getting into Hulk's brain to turn him against the Avengers. The scene, according to MTV, leads into an even larger-scale battle, although we don't have any details on that yet.
Also, the floating repair station for the Hulk Buster armor is pretty cool.
They're going to save some surprises for opening night, right?
