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.

Comedy is a meritocracy. If you are funny, you are there. If you are not, you are out.

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.

People who know and read comics know that there's a huge diversity amongst the types of stories. Nobody ever goes 'how many more of these movies based on novels are there going to be?!'. People laugh at that question and they go novels, there are all different types of novels. But there are all different types of comic books, they just happen to have drawings on the cover!

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 those with knowledge of the comics may expect things that will not be happening in the movies. Those who don't know what has happened in the comics will be shocked at what we do.

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.
