Here’s a revelation that shouldn’t come as a shock, but it’s nice to have confirmation on. Marvel Studios will be doing a sequel to Doctor Strange at some point in the future.
In a larger interview with Cinemablend, Feige comments on Doctor Strange:
“Sometimes it’s where do those characters pop up? [Doctor] Strange, you know, whenever we do another Strange one, which we will do, it will be a number of years from the first Strange, and yet he’s a very big part of [Avengers:] Infinity War. So it is just a good problem to have when you have too many beloved characters that people want to see more of, whilst keeping to our core belief that we need to keep exploring nuance and keep doing different types of things.”
Right there he says “we will do” another Doctor Strange movie, and with the last one already being nearly two years old as of this year; it wouldn’t be shocking to see it as one of the three 2020 movies Marvel has scheduled. With Guardians of the Galaxy Vol. 3 pretty much guaranteed for the May date, Black Widow likely for July, a Doctor Strange sequel would fit very well in the November 2020 slot.
