It has been all but confirmed that a sequel to 2016's Doctor Strange is a part of the Marvel Cinematic Universe's post-Infinity Saga lineup. However, despite news that director Scott Derrickson had signed a deal to return for Doctor Strange 2, very little information regarding the film's development process has been made available.
Doctor Strange star Benedict Wong provided some potential insight while speaking at Denver Pop Culture Con over the weekend. Wong made his MCU debut as the character Wong in the 2016 film, a role he subsequently reprised in 2018's Avengers: Infinity War and this year's Avengers: Endgame.
Wong was asked if he could offer any information regarding Doctor Strange 2, to which he replied, "I know they've now got a writer on board who I met at the Endgame premiere. So I think that may be happening some time next year."
It is unclear whether Wong meant that the film would begin production next year or that it would be released that year, but it is currently assumed to be the former. At any rate, the confirmation that the film has locked down a writer seems to indicate that it is well on its way. While Wong's statement is by no means official, it appears he is at least preparing for the project to begin.
Notably, early reports suggested that Doctor Strange 2 was eyeing a 2021 release date. However, more recent reports claim that the film could, in fact, arrive at some point in 2020. While these reports should obviously be taken with a grain of salt, they do at least someone line up with Wong's comments.
Marvel Studios' list of post-Endgame films currently includes Doctor Strange 2, as well as The Eternals, Black Widow, Shang-Chi and Guardians of the Galaxy Vol. 3. The studio plans to release three films in 2020, with Eternals and Black Widow expected to fill two of those slots. The third remains up in the air.
Marvel will make some sort of official announcement regarding the specifics of their future releases sometime relatively soon.
