"Avengers: Age of Ultron" set photos and unofficial behind-the-scenes footage from the shoot in Korea have begun to surface, including a very quick look at the new look for Captain America. With a few more days of the shoot in the can, JoBlo.com has compiled a group of much clearer photos featuring Chris Evans in the new Captain America costume, as well as Korean news reports showing the behind-the-scenes action of the filming.

Of note on Cap's new uniform is the presence of an actual Avengers "A" insignia on his shoulder, possibly signifying that the Avengers have struck out and created an official team -- with official uniforms -- rather than the quick, thrown-together crisis squad of the first film. This is the first time in any of the photos that the iconic "A" has been seen on any of the characters, so it's anybody's guess what its actual meaning could be.

Check out the photos and footage below.
