As expected when Marvel released Avengers: Age of Ultron Comic-Con posters featuring Scarlet Witch and Iron Man, they turned out to be just the first of many. Now it's Black Widow and Captain America jumping into the war against Ultron (James Spader) and his army of "legionnaires". I expect there will be more of these, probably each day until Marvel's panel on Saturday.
Avengers: Age of Ultron opens May 1st 2015.
