Marvel has marked the beginning of filming on Captain America: The Winter Soldier by releasing a first photograph from the production.
Chris Evans, who plays the super soldier, is seen with his back to the audience in the SHIELD offices.
The movie will continue exploring idealist hero Steve Rogers/Captain America's disarray after 60 years in hibernation, a theme that is referred to in The Avengers.
Anthony and Joe Russo are currently filming Captain America: The Winter Soldier, set for release in North America on April 4, 2014.
The superhero will face the Winter Soldier, an elite assassin who is in fact his friend Bucky Barnes, who was thought dead. Scarlett Johansson, Anthony Mackie, Samuel L. Jackson and Robert Redford will also star in the upcoming blockbuster.
