Doctor Strange

Not much is known about Doctor Strange, so I'll just give you what's available. Kevin Feige confirmed it's happening, that the movie will be his origin story, the movie will be part of Phase 3, and that he is tentatively lined up to be in Avengers 3.

As far as casting goes rumors include Peter Dinklage, Patrick Dempsey, Liam Neeson, and Hugh Laurie. However, Marvel is paying attention to one man in particular, Justin Theroux, the main who wrote Iron Man 2 (I hope his acting is better than his writing).

We can expect this movie in April 2016, chronologically following Ant-Man the previous November.
