It's kind of weird to meet people that grew up in films who are still in touch with reality.

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 don't know that we'll get into Earth 1 thru 616 in any one moment anytime soon.

People say 'Scott's [Derrickson] movies are kind of scary, is this a horror movie?' Of course, [Doctor Strange] it's not a horror movie. But what Scott has done so well in the best of his films is have one foot completely in the real world and one foot in this whatever supernatural sub-genre he was playing with.

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.

I don't know if it was written off in that single line in Thor. It was given another way of looking at it. There are a couple of lines in Thor basically saying that science and magic it gets to a point where what's the difference. And I think we're continuing that.

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.
