The Avengers 2 'Age of Ultron' co-producer, Kevin Feige has dropped some major spoilers that tickled Marvel fandom's excitement.

"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" he explained.

"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."

Feige continued, "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 organization 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 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."

However, when it comes to the question whether another 'The Hulk' movie is underway, Feige was quite uncertain.

"It's exciting, because he hasn't been in any other film, so you can expect to have a lot of Bruce Banner and Hulk in Age of Ultron. Where we go after that ? We'll see. It will be a little while before we figure that out but, we do think there's plenty of opportunities with the Ruffalo Banner."

Apart from the fact that the elite superhero roster will grow with the addition of Magneto's twins Scarlet Witch (Elizabeth Olsen) and Quicksilver (Aaron Taylor-Johnson), fans are excited about the malevolent Ultron who will gather an army of robots to take down the Avengers.

Director Joss Whedon has recently announced on Twitter that filming has wrapped and paid tribute to the people who "made the movie" and made his year.

The stellar cast of the much-awaited sequel of Avengers was present during the recently concluded San Diego Comic-Con 2014, including the actor who will play Thanos, Josh Brolin.

Avengers 2 'Age of Ultron' is expected to hit theaters on May 1, 2015 under Walt Disney Motion Pictures.
