Tony Stark is a man with interesting alliances and those alliances are about to be tested in Marvel’s Avengers: Age of Ultron. When his attempts to reignite a dormant peacekeeping program goes predictably wrong, the villain that is Ultron emerges and is seeking to end the very existence of humanity. Of course that would be easier if the hero super-team, The Avengers, wasn’t always fighting against one another, but really what fun would that be? At the end of this trailer we get an extended look at the fight scene between Iron Man in Hulkbuster Armor and the fiercest Hulk ever. We’ll have to wait till May 1st to see how this disagreement shakes out and whether or not the Avengers can save the planet, again.
