San Diego Comic Con News:  Marvel Studios has unveiled two more concept art posters for Joss Whedon’s Avengers: The Age of Ultron.  The two new designs, both created by artist Ryan Meinerding, continue the "surrounded by robots" theme of the first two concept posters that were released yesterday and which depicted Iron Man and Scarlet Witch being mobbed by hordes of Ultron’s minions (see "Marvel Releases Concept Art Posters for 'Age of Ultron'").  
 
The poster for Black Widow pulls back to more of a medium shot, revealing the vast number of the attacking robots.  In the background it appears that there are a number of bots that have gone airborne, thanks to a blue streak of what may be Quicksilver races through their midst, while in the right foreground, a large green Hulk hand indicates that Marvel’s “not so jolly green giant” is heavily involved in this battle as well.
 
The Captain America poster, which like the Black Widow design was first released to the MovieWeb site, returns to the medium close-up vantage point of the posters that were released yesterday and provides a good look at the robots’ construction with their curiously arched backs.  Joss Whedon’s Avengers: The Age of Ultron is slated to debut on May 1st, 2015.
