Continuing the build-up to the Sept. 9 release of Captain America: The Winter Soldier, Marvel has released three more featurettes -- one of which debuted this morning on Comic Book Resources.

In the first, directors Anthony and Joe Russo and star Chris Evans discuss what makes Captain America such a compelling character, while in the second, Sebastian stand and fight choreographer Thomas Robinson Harper highlight some of the training required by the film. And in the third, the Russo brothers and Evans talks about what Anthony Mackie brings to the role of Falcon.

Captain America: The Winter Soldier, which also stars Scarlett Johansson, Samuel L. Jackson, Frank Grillo and Cobie Smulders, will be available for home viewing on Sept. 9.
