It looks like the cast of the Dr. Strange movie is filling out.
12 Years a Slave star Chiwetel Ejiofor is in talks to take on the role of Baron Mordo in the upcoming Doctor Strange film. Trained by the Ancient One, like Strange, Mordo becomes a villain in the comics. From the rumors it looks like Mordo might be a friend and fellow sorcerer. It might be a case of friends turned enemies, or a twist in the film. Only time will tell, but so far solid casting for the Phase Three film.
