The "Avengers: Age of Ultron" filming is in full swing, and no less than Marvel's president of production Kevin Feige shares choice words for the highly anticipated film.

From IO9, Whedon talks about the Avengers Tower, which will be a major setting in the film, especially with the brand new established context after the events of "Captain America: The Winter Soldier:"

"Last time we saw Stark Tower, from The Avengers, it had gotten beat up a little bit thanks to Hulk and thanks to Loki and the Chituari, and Pepper and Tony were standing over a table looking at plans. That's where we pulled out and all the letters had fallen away except the 'A' in Stark. So what they were doing was retro-fitting for The Avengers. And that's what we see in this next film."

Stark giving up his own headquarters for the team means he is heavily investing his time 'superheroing.' Being the businessman that he is, there must be an underlying interest:

"S.H.I.E.L.D. is gone - for people who are following along. S.H.I.E.L.D. was disbanded and brought down at the end of The Winter Soldier because it turned out to not be the best organisation ever. So Tony's bank-rolling The Avengers now. And he's bank-rolling their headquarters. So it's now Avengers Tower.

Tony designed it so in addition to a hanger(sic) for a brand-new Quinjet, laboratories, places where he can build and store his Iron Man suits, there are I believe two bars. Beautiful multiple space living rooms which are perfect for parties and social gatherings. But it's a primary location in the film this time around."

The Avengers will carry more of Tony Stark's imprint than the first film, and they are now an established team, even an organization-the one that will replace SHIELD.

Another known highlight of the film that has been hinted is the concept art of the Hulk battling Iron Man's known Hulkbuster armor. Once and for all, Feige confirms that will happen in the film, but there's more where that came from:

"There are a lot of scenes that you should be getting excited about. That is certainly one of them. I think I said a long time ago when Joss [Whedon] first did his six-page or 10-page outline for Avengers, there was a lot of work and the movie's adapted quite a bit since then, but there were like six or seven signature things just in that. I said 'Joss, even if we don't do anything else. Just do these seven things, that's enough for the movie. Now let's get to work and put it all together.' Those things are in the movie and are amazing, of which that sequence is one."

 We are left to guess what those other six are, but it's better for all parties concerned that we just watch it all on May 1, 2015.
