TEASER: "Avengers: Age of Ultron"

After leaking online earlier this afternoon, Marvel has released the official teaser trailer for next May's Avengers movie, guaranteed to make a billion dollars without breaking a sweat. Looks like they're going for a darker tone in this, as rumor has it the Avengers will disband by the end of the film, leading to the Iron Man/Captain America battle destined to take place in the third Captain America movie. James Spader supposedly did some motion capture work as Ultron here- hopefully this film will mark the first in the MCU to have an actual, memorable villain.
