Interesting quotable from Anthony Mackie describing TWS as "The Avengers 1.5"...
First, I’ll say that being a part of it is great. I think that Marvel has it down to a science and they’ve been very deliberate about what they want and what they don’t want out in the world. And they’re very focused on timelines as far as releases and stuff. This movie, "Captain America," has kind of become "Avengers 1.5"; if you look at the cast they’ve put together, if you look at the number of characters that are in this movie. I mean, it’s a huge number of superheroes and characters. The basic idea is that you have Captain America, Black Widow, and Falcon that get together to take down the Winter Soldier.
