Back in December it was confirmed that Doctor Strange director Scott Derrickson is officially on board the sequel to Marvel’s 2016 origin story for the Sorcerer Supreme, and now That Hashtag Show is reporting that he’ll be joined by his Sinister and Doctor Strange screenwriter C. Robert Cargill.

Details on Doctor Strange 2 are scarce, but we do know that Benedict Cumberbatch will be back as the Master of the Mystic Arts along with Benedict Wong as Wong, and that Marvel is looking to begin production on the movie in the spring of 2020 for release in May 2021.

Back in 2018, Cargill had teased where Doctor Strange 2 might go, with the screenwriter stating:

“Nightmare will be the villain. Me and Scott have not laid the groundwork for it but what I can say is that I have a feeling that whatever Nightmare is involved with, Baron Mordo, being somebody who considers himself the defender of natural law will have something to do with it. For those of you who have ever read the comics, you know that Baron Mordo has a very particular arc, and that’s something we discussed with Chiwetel while working on the first movie. And part of the reason Chiwetel wanted to play Mordo was because he has a definitive ending as a character and it’s such a fascinating ending. And I do know that whether we’re attached or not, that Marvel plans on working towards that ending and fully realizing Mordo as more than just a cardboard cutout villain, but actually taking him to kind of Loki levels of awesomeness. That’s the goal with him.”

Although Marvel is keeping its post-Avengers: Endgame plans close to its chest, we do know of several movies that the studio has lined up for Phase Four of the MCU, with Doctor Strange 2 set to be joined by Spider-Man: Far From Home, Black Panther 2, The Eternals, Black Widow and Shang-Chi. Guardians of the Galaxy Vol. 3 also remains on the table, although Marvel is yet to find a replacement for director James Gunn, and it’s unclear when this project might move forward.
