Marvel loves the San Diego Comic-Con and has unveiled four new pieces of concept art for AVENGERS: AGE OF ULTRON featuring Captain America, Scarlet Witch, Black Widow and Iron Man battling the Ultron robot army which is probably part of a larger banner - note portions of Hulk's hand and Thor's Mjolnir in Black Widow's poster. If we get more images soon - I'll update this post.

Looks like the Avengers definitely have their hands full.

AVENGERS: AGE OF ULTRON opens on May 1, 2015.

NEXT DAY UPDATE: Here are the next two pieces of concept art featuring Hawkeye, Quicksilver and The Vision. They do all fit together as originally thought!
