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.

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.

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.

Filmmakers are anxious about what other people are working on.

There's nothing more disheartening than seeing a movie and going oh, that doesn't work, or it didn't inspire us. Versus seeing a movie that is 'this is so awesome!'. Oftentimes, a really good movie just inspired you to go and make movies!

I'm not a huge comic book fan, but I'm a closet fan of certain Marvel heroes, two of those being Iron Man, and the other being Guardians of the Galaxy, which I'm looking forward to.

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.
