Following on from a special screening of footage from the sequel earlier this week in the United Kingdom, Marvel Studios chief Kevin Feige discussed a sequence that was screened for media which involved both Tony Stark's Hulk-busting armor taking on the Hulk himself. He also went into details regarding the newly-designed Avengers Tower. Of the latter, Feige tells IGN:
"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... 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 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."
In regards to the Hulkbuster vs. Hulk battle sequence, Feige says:
"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."
The footage shown the other day also included a scene with Quicksilver and Scarlet Witch fighting alongside Hawkeye on a demolished Italian street.
