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.

Once that Gauntlet is on, as the poster of Doctor Strange says, "the impossibilities are endless."

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.

Filmmakers are anxious about what other people are working on.

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.

We put in all the great ideas that can be brought into the film [Doctor Strange] in the service of introducing the world to an audience who's never heard of it and doesn't know it from a hole in the wall. And we thought that an inter-dimensional girlfriend that's the daughter of an inter-dimensional demon-esque creature was a step too far in introducing this world.

When we bring the filmmaker, we bring somebody to help us elevate the material with those things, to help us do something different with all of those resources at their disposal.
