On the heels of the reveal of the exclusive concept art poster for 'Ant-Man,' Marvel Studios has also unleashed two concept art posters for 'Avengers: Age of Ultron' at Comic-Con 2014, featuring Elizabeth Olsen's Scarlet Witch, Robert Downey Jr.'s Iron Man, and a whole bunch of nasty, antagonistic robots. UPDATE: Keep checking back as Marvel releases the final posters in this series.

Earlier this evening we got a look at an exclusive concept art poster for 'Ant-Man' from Comic-Con, and now Marvel has gifted us with two more posters -- this time for 'Avengers: Age of Ultron.' In the first of both posters featured below, we see Elizabeth Olsen's Scarlet Witch surrounded by robots, one of which has an arrow through its eye -- one that came from Hawkeye, perhaps? In the second, we see Iron Man being clawed at by the evil bots while he blasts another in the face. Both posters offer some intriguing concept art that puts our characters in a rather claustrophobic situation. We can't wait to see how this translates to the big screen.

Marvel has also added concept art posters of Black Widow, Captain America, Hawkeye, and Quicksilver, all embroiled in the same bot-heavy combat -- we assume that when placed together, all of these posters will make up one large scene.

'Avengers: Age of Ultron' will be featured in the Marvel Studios panel this Saturday in Hall H at Comic-Con, and we'll bring you more details then. The film also stars Scarlett Johansson, Mark Ruffalo, Jeremy Renner, Chris Hemsworth, Chris Evans, Samuel L. Jackson, Aaron Taylor-Johnson, James Spader, and Paul Bettany, and hits theaters on May 1, 2015.
