Over the course of production, 'Captain America 2' photos were leaking left and right from the set, giving us a bootleg look at Chris Evans' Steve Rogers, Scarlett Johansson's Black Widow and Sebastian Stan's Bucky Barnes (aka "The Winter Soldier"). But as we get closer to the premiere date, more new images, stills and concept art have hit the web.

Get a look at all the latest 'Captain America 2' photos in our gallery ahead.

While Thor is busy handling his own business post-'The Avengers' in 'Thor: The Dark World,' the Cap heads to Washington, D.C. along with Agent Rominoff to deal with a shadowy new threat. This threat, of course, is the infamous The Winter Soldier, taken from the classic 'Captain America' comic book arc. From the looks of the 'Captain America 2' photos, however, Barnes is not himself as he's been brainwashed and physically enhanced to become an assassin.

Co-directors Anthony and Joe Russo ended up creating more than just your standard superhero movie, but describe the sequel as more of a political thriller akin to the world of the late-Tom Clancy. Speaking to USA Today, "['The Winter Soldier' is] one of the best comic runs in the last 20 years, one of our favorite comic runs of all time, and we really want to do it justice. It was important to us to make sure he just jumped off the page to the screen."

Get a taste of The Winter Soldier himself, the return of the Cap, and some new faces -- like Anthony Mackie's Falcon -- in the 'Captain America 2' photos below. The film is set for release on April 4, 2014.
