Now that production is underway on "Captain America: Civil War" in Atlanta, pictures have started to emerge of the cast on set. After a few days of shooting in civilian clothes, new photos published over on Just Jared show off not only Chris Evans and Anthony Mackie in full hero gear, but they give us our first look at Frank Grillo suited up in his Crossbones gear.

Grillo, whose character Brock Rumlow previously appeared in last year's "Captain America: The Winter Soldier," will receive a significant upgrade for next year's "Civil War." Judging by the costume, Grillo's character has finally taken up the Crossbones mantle and has the body armor and mask to match.

Additionally, while Captain America's uniform looks mostly in line with the one he wore in "Avengers: Age of Ultron," his partner Falcon is sporting a new look that incorporates the character's red color scheme from the comics.

"Captain America: Civil War" opens on May 6, 2016.
