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 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 think that's there are a couple of reasons for that. One is as you're introducing the fourth and fifth versions of these MacGuffins that we've been playing with for a long time, you wanna do something different with them and not just have them be an object passed around. So the notion that something is inherent in the literal body of one of your lead heroes is interesting. And the idea that the Eye of Agamotto's a great relic over the course of Doctor Strange comics anyway.

I do think we've looked at this film [Doctor Strange] not with any direct genre comparison but as a play on the supernatural genre. Certainly more so than we've done in the past, which is what makes his journey from person that doesn't wear a cape to person who does wear a cape - cloak, much more unique than we've seen in the past.

I think when comic book fans hear parallel dimensions or multiple dimensions they think of Earth 616 and Earth 617 and Earth 618. That's all possible.

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.

The super-powered girlfriend for [Doctor] Strange wasn't in the first issue. There's a lot of backstory required for her, which is one of the reason we didn't go that way. There's so much to set up in this. I think it's always a huge mistake when you throw the kitchen sink and everything in the first movie.
