12 Interesting Age Of Ultron Theories Based On The Trailer

12. It Will Link In With Doctor Strange

In the trailer, we see an old building set in the mountains. We then see Captain America kicking an old door open, just prior to heading down some stairs in what we assume is the building in question. It's safe to assume that this building is not in the United States and, given that we've seen set photos of Captain America in Asia, these mountains are probably the Himalayas. The Himalayas are, of course, the place where Doctor Strange sought out Earth's Sorcerer Supreme - the Ancient One - and we'd bet our bottom dollar that he will be found in - or at least linked to - this very building when the Doctor Strange movie comes out.
