The immediate reaction following the Comic-Con 2013 reveal of 'Avengers: Age of Ultron' was excitement...followed shortly thereafter by lots and lots of questions. In his only interview after Marvel's Comic-Con panel, Joss Whedon answers your questions about 'Avengers 2' and explains what he has in store for Ultron and the sequel.

The 'Age of Ultron' crossover event in the Marvel comics earlier this summer was disappointing to say the least. It also seemed to be a storyline that would be very difficult to adapt into a feature film considering Marvel's current contractual agreements (Spider-Man and Wolverine both play big parts in the story). With the subtitle of 'Avengers 2' revealed to be 'Age of Ultron,' many fans were left wondering how Joss Whedon and Marvel planned to pull this movie off.

And the answer? They don't.

Whedon says that 'Avengers: Age of Ultron' isn't based on the comic storyline at all, it's just borrowing the title.

A lot of people, because we called it 'Age of Ultron' and there was an 'Age of Ultron' book recently, assumed that was the storyline we were doing, which is not the case. We're doing our own version of the origin story of Ultron.

Well, that would seem to eliminate many of the questions about how to adapt 'Age of Ultron' for the screen. Yet, how do you tell the origin story of Ultron without Dr. Hank Pym, who won't make an entrance in the Marvel Cinematic Universe until Edgar Wright's 'Ant-Man,' which isn't set to hit theaters until after 'Avengers 2'? Whedon confirms that Pym/Ant-Man won't be a part of his Ultron origin, explaining:

We're basically taking the things from the comics for the movie that we need and can use. A lot of stuff has to fall by the wayside. But we're crafting our own story, where his origin comes directly from The Avengers we already know about.

And, based on that, we offer this theory: The teaser shown at Comic-Con highlights an Iron Man helmet being banged and reshaped to the classic Ultron helmet we all know and love. Could it be possible that the remote Iron Man suits that were created by Tony Stark in 'Iron Man 3' and the arc reactor he throws into the ocean will somehow give birth to Ultron?

That's just speculation but you can watch the full 5-minute interview with Marvel below to see what else Joss Whedon has to say about 'Avengers: Age of Ultron.'
