Paul Rudd's miniature hero took down Falcon (Anthony Mackie) in July's aptly titled Ant-Man (see video below), and it's an unfortunate encounter Sam Wilson would be loath to forget. Scott Lang will enter the Civil War world to help Caps (Chris Evans) free the Winter Soldier (Sebastian Stan), but the mechanical engineer may soon find himself in the thick of battle.

Believed to be on Team Captain America, Ant-Man was spotted filming side by side with the First Avenger in Leipzig, Germany. It is believed Rudd could also have scenes with Iron Man (Robert Downey Jr.), Black Widow (Scarlett Johansson), and War Machine (Don Cheadle), three members of the opposition that were seen filming in the same area, according to Comic Book Movie.
