Marvel's Kevin Feige is continuing his epic press run for Captain America: The Winter Soldier this week, where he has been talking about all things related to the Marvel cinematic universe. Today, he is praising James Spader's work as the villain Ultron in Avengers: Age of Ultron while teasing the character roster change as this franchise continues to move forward, into the future.

" Introducing the new characters is going to be a lot of fun for the movie. That ever-changing roster is very important in the Marvel's The Avengers comics, and so how do we start to play with that [on the big screen]? Also our bad guy is great. I think people are going to very, very excited to see what we're doing with the voice that Joss [Whedon] is bringing to life with James Spader for Ultron. We love Ultron from the comics, and have always loved Ultron, and at no point do we want him to just be a robot. We want him to have an extreme personality and attitude, and James Spader is doing an unbelievable job. Again, for us it's always about subverting expectations. Whenever you think you know what's coming next, we surprise people or deliver it in a slightly unexpected way. And James Spader is doing that with Mr. Ultron."

Marvel Studios: Assembling A Universe debuts this Tuesday, March 18, and it promises to bring a first look at Avengers: Age of Ultron. But just how much of the movie will we see, since shooting has just starting to begin? Kevin Feige went onto tease this sneak peek.

"They're advertising it as a first look, and that is an honest statement. We don't start filming for another week and a half, so you're not going to have a lot of first-unit footage because it doesn't exist yet. But you certainly get more than just a peek at some of the new fun things we have in store."

We know that some Hulk footage has been shot without the cast, and we know that some Quicksilver and Scarlet Witch footage has also been shot. Will we get to see that tomorrow? We'll have to tune into ABC for our answer.
