New Captain America 2 pics reveal Black Widow's return

Production on Captain America: The Winter Soldier has officially begun. But Chris Evans isn't the only Avenger suiting up for the sequel. Scarlett Johannson also reprises her role as deadly assassin, Black Widow. Monday night, both actors were spotted on set while shooting in Los Angeles.

These behind-the-scenes photos were obviously taken from a distance. Despite the grainy quality, you can see that each character has a new look. Captain America has a revamped costume, and Black Widow is sporting a longer, straighter hairstyle.

Judging by the harness and wires present, we're assuming a stunt was being performed. With the Winter Solider on the loose, Cap will need all the help he can get. Not only is Black Widow back in the fold, but Nick Fury (Samuel L. Jackson) and Maria Hill (Colbie Smulders) will also appear.

Captain America: The Winter Soldier opens in theaters April 4, 2014.
