We're just as antsy as you are when it comes to anticipating that first look at The Avengers: Age of Ultron, Marvel Studios' ridiculously anticipated follow-up to the third highest grossing movie of all time, The Avengers. While production doesn't begin for another week, fans have been promised a first look at the sequel during this week's ABC special Marvel Studios: Assembling a Universe, which will chronicle the studio's big-screen success beginning with Iron Man all the way through next year's Avengers sequel.

Promos for the one-hour special are already teasing new footage from both Captain America: The Winter Soldier (4/4) and Guardians of the Galaxy (8/1), but what about Age of Ultron? How much should we expect to see? We asked Marvel Studios head Kevin Feige about that during a recent chat.

"They're advertising it as a first look, and that is an honest statement," he told us. "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."

More than just a peek sounds more than okay to this Marvel dork, and though he didn't give up much, we also had to grill Feige on what to expect in the Avengers sequel, due out on May 1, 2015. One thing he seems really excited about is the work James Spader and Joss Whedon are doing on the film's villain, Ultron.

"Introducing the new characters is going to be a lot of fun for the movie," said Feige. "That ever-changing roster is very important in 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 be 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 Spader is doing that with Mr. Ultron."

Stay tuned for more with Kevin Feige as we inch closer to the April 4 release of Captain America: The Winter Soldier.
