We know that the upcoming Avengers: Age of Ultron pits the Hulk against Iron Man — appropriately wearing his supersized Hulkbuster armor — but until now, we didn't know why the two colleagues were fighting. Tonight, in a new clip from the movie aired at the MTV Movie Awards, we learned the answer. Be aware that the clip below, which features fantastic footage of The Hulk and Tony Stark tussling through city streets, contains mildly significant spoilers for Age of Ultron.
The clip corroborates fan theories that the Hulk is under the sway of a nefarious third party. We don't see that other character in the clip, but it does at least show that two of the core Avengers aren't fighting each other because of mutual dislike, but an outside influence. Not long to go now to find out exactly how the Hulk gets so angry — the movie sees general release in the US on May 1st.
