Captain America: The Winter Soldier featurette on the Black Widow
I've said this before - I'm just not a fan of Captain America. The first movie did not really help change my mind either. I thought it was pretty boring. With the inclusion of Black Widow in sequel, however, things may just be a little more interesting.
Watch this new Captain America: The Winter Soldier featurette on the the most kick-ass OS herself - the Black Widow.
