Will the Doctor Strange movie be part of Marvel Studios "Phase 3" films?
If Stan Lee is correct, it seems likely.
Stan Lee attended the recent Savannah Film Fest where "The Man" answered audience questions with one being about future super hero movies (via The District).
Not only does Stan Lee say that a Doctor Strange movie is being made, but also Black Panther and the Inhumans.
“Oh they are all being made into movies! I can tell you there will definitely be a Dr. Strange movie! They are working on Antman, which requires really small cameras! Black Panther is being developed, one of my favorites…the Inhumans…All the hero’s will eventually be made into movies.”
All three of the movies that Stan Lee mentioned have been said to be in development at one time or another. The latest in regards to Doctor Strange is that he will be appearing in Thor 2, and we here at Cosmic Book News think Strange might be filling Coulson's role in the Marvel "Phase Two" movies of bringing them all together, much like Coulson did for Marvel's "Phase One" movies and The Avengers.
It's quite possible that Ant-Man, Doctor Strange and the Inhumans could make up Marvel's "Phase Three" movie leading to "The Avengers 3." With Thanos said to be the big bad guy of "The Avengers 2," who would fit for the third? Ultron?
