Avengers: Endgame doesn't hit theaters for several months, but sources have told The Hollywood Reporter that a Doctor Strange sequel is already in the works. Sure, the good doctor was dusted along with half of all living things in the universe in Avengers: Infinity War. We never believed they were all truly gone for good, and this news confirms it. Marvel, however, declined to comment.
There's no script yet; that should be in the works early next year. But per The Hollywood Reporter, Benedict Cumberbatch will return as Stephen Strange, along with Benedict Wong as his right-hand man, Wong. Rachel McAdams is rumored to be returning as well, as Stephen Strange's somewhat-reluctant love interest.
That's all the details we have right now, but the ending of the first Doctor Strange certainly set things up for Baron Mordo (Chiwetel Ejiofor) to return as a worthy opponent. Mordo became disillusioned when he discovered that the Ancient One (Tilda Swinton) he followed so devotedly achieved her long life by drawing on power from the Dark Dimension. A post-credits scene showed Mordo taking away the mystical energy that another acolyte had been using to walk despite being paralyzed in an accident. So it makes sense he would play some role in the sequel.
