The more films we make the more we get to deal with those pre-existing relationships. But when it comes to a movie like Ant-Man or Guardians or certainly Doctor Strange, it's just bringing to life stuff that's already been there in the comics and we finally get a chance to do it on the big screen.

The funny thing is I showed my daughter E.T. recently, and she was like, it's Pete's Dragon. It's a boy, who makes friend with a creature, and has to say goodbye at the end. I'd never made that connection!

The Avengers films, ideally, in the grand plan are always big, giant linchpins. It’s like as it was in publishing, when each of the characters would go on their own adventures and then occasionally team up for a big, 12-issue mega-event. Then they would go back into their own comics, and be changed from whatever that event was. I envision the same thing occurring after this movie, because the Avengers roster is altered by the finale of this film.

I don't think it's a mistake to put every great idea into the first movie, because I've always said there won't be a second movie if you go 'we'll hold back these ideas for another one.

I don't know that a movie like Doctor Strange couldn't have been the second or third film we made. I don't think we're doing anything in that requires past viewing, as opposed to Civil War which we wouldn't have done as the first or second movie because so much of that film is based on the pre-existing relationships between the characters.

I was making Marvel Studios movies, Amy Pascal was running Sony. Occasionally, she would share drafts with certain people at the studio and I would read them, and see cuts of the movies. But what I've learned with is that I'm no help whatsoever giving passive comments on other people's projects.

You've heard me talk about the quantum realm in Ant-Man which was certainly designed for that movie and for that story to take the notion of somebody who has the ability to shrink to another level we've never seen before, but as we were doing that, and studying it and talking to the science advisors who are always more than willing to spend an afternoon with us and talk about these amazing things - the quantum realm is another dimension.
