Most obviously it [Doctor Strange] will introduce a new character who will be in play in the universe, but once you have gotten an audience to buy into a new concept then it's fun to keep, to play-off, or spin-off that concept down the line.

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.

The only thing I'll say, and I'm sure everyone says this, is stick with it. I'm not shy about telling people about the fact that my dream was to go to USC film school when I was growing up in New Jersey. I got rejected five times. You just keep going, keep going, keep going.

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.

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.

I think it's human nature to go and to watch things that are done, and see the flaws, but I cannot think of anything that we would want to go so far as to completely change or redo to be honest with you. I think there are characters, you look at the Thor: Ragnarok trailer, there are characters that can evolve and can continue to change and grow throughout.

Being authentic in the way you'll see today on the sets [of Doctor Strange] that Charles Wood has designed for us, being authentic in filming, as we did for the first week on production on this in Nepal and in Kathmandu. It was important to us to make it feel like these were real locations and real things.
