When you get into individual characters certainly there's been things that have been updated .

We are fortunate to have such an esteemed filmmaker join the Marvel family. The talents Ryan [Coogler] showcased in his first two films easily made him our top choice to direct 'Black Panther.' Many fans have waited a long time to see Black Panther in his own film, and with Ryan we know we've found the perfect director to bring T'Challa's story to life.

Filmmakers are anxious about what other people are working on.

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.

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.

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.

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.
