"We don't have to have him [Pym]. It works very simply — this is Marvel cinema, not Marvel comics. One thing [Marvel Studios head] Kevin Feige has a genius for is knowing what to hold onto and what to let go of. You can invoke the feeling you had and play with the characters you love and remain true to the needs of the film."

Deal with it

Whedon: "Well, because there was a book called 'Age of Ultron' quite recently, a lot of people have assumed that is what we're doing, but that is not the case. We're doing our own version of the origin story for Ultron. In the origin story, there was Hank Pym, so a lot of people assumed that he will be in the mix. He's not. We're basically taking the things from the comics for the movies that we need and can use. A lot of stuff has to fall by the wayside."

"We're crafting our own version of it where his origin comes more directly from The Avengers we already know about. It's a little bit darker than the other film because Ultron is in the house. There's a science fiction theme that wasn't there in the other one. Ultron is definitely something that evolves, so we're going to get together a couple of different iterations. Nothing can be translated exactly as it was from the comics; particularly Ultron."

"It's very much a global Avengers film. A lot of the movie has to do with their place not just in America, but the world. Part of the fun for me, definitely this time around, is writing Hawkeye. He did get possessed pretty early by a bad guy and had to walk around all scowly for most of the movie so now it's nice to actually have the character there and see him interact with the other guys."
