To promote its movie about a group of superheroes fighting to free humanity from enslavement by a cold, heartless machine, Marvel demanded that fans spend the morning on Twitter, tweeting promotional hashtags to its satisfaction, until it deigned to give them a new trailer.


Anyway, it worked, so now you can see the above clip of Avengers: Age Of Ultron, which builds on previous clips by delving a little more into Ultron’s back story, gives you your first brief glimpse of Vision, brings in a potential romance between Hulk and Black Widow—all the benefits, in other words, that make submitting to a mechanical overlord worth it. Age Of Ultron will be released on May 1, 2015, but only if enough people Instagram pictures of themselves wearing Captain America underwear.
