There is a lot to look forward to in terms of the films for MCU Phase Four that are lined up.
Doctor Strange in the Multiverse of Madness has been in theatres less than a week and is already making waves. The film was released as part of the MCU Phase Four. It follows the events of the first Doctor Strange film, Avengers: Endgame, WandaVision, and Spider-Man: No Way Home.
By the looks of it, it's clear that the future of the MCU has been determined well in advance. As we will enter the last part of Phase Four next year, there is a lot to look forward to in terms of the films that are lined up. Will the third Doctor Strange film be a part of it?
Marvel has not confirmed that there will be a threequel to the Doctor Strange series yet. But there is no reason to assume we will not be getting a film in the future. It will definitely not be a part of Phase Four and so far it's not a part of Phase Five so far either. Currently, we have a rough idea of what can kick off Phase Five that includes Blade, Deadpool, Captain America, Shang-Chi, and the much-anticipated X-Men film. In Multiverse of Madness, we were also introduced to several future Marvel films including a Fantastic Four film.
With a multiverse opened, we will surely see Doctor Strange in many other worlds. If it so happens that the plot leads to the creation of a third Doctor Strange film, it will be in the latter half of Phase Five.
The plot of Multiverse of Madness was a culmination of several plotlines. The film also ended with a pretty huge cliffhanger with the mid-credits scene also introducing Charlize Theron as Clea. If this introduction is not dealt with in any of the innumerable other MCU films that are set to release, it could possibly be the plot of the next Doctor Strange Film. With multiple universes at the disposal, the story can take place as the plot of all these universes has developed over the course of Phases Four and Five.
Benedict Cumberbatch who plays Dr. Steven Strange has also announced that he will be taking a break from acting. So the next movie will also pick up after he ends his hiatus.
Cumberbatch as Steven Strange will reprise his role along with Sorcerer Supreme Wong. Xochitl Gomez as America Chavez may also be a part of the next film along with Michael Stuhlbarg as Nicodemus West and Rachel McAdams as Christine Palmer.
It seems unlikely that Elizabeth Olsen as Wanda Maximoff / Scarlet Witch will be coming back to the next film. There is also Charlize Theron as Clea who could potentially be a part of the film, as well.
The films slated for release the next year do not include another Doctor Strange film. If anything, the next film could be a part of the next MCU Phase. We can expect to see the film post-2023 only. Phase Five goes on till 2028.
