Marvel is bringing you “Doctor Strange in the Multiverse of Madness” on May 7, 2021, the studio announced during its panel at San Diego Comic-Con on Saturday.

Marvel Studios boss Kevin Feige said the “Doctor Strange” sequel will be “the first scary MCU film.” But, Feige joked “It’s gonna be PG-13 and you’re going to like it!”

It was revealed during the panel that the Disney+ series “WandaVision” will lead directly into the events of “Doctor Strange in the Multiverse of Madness,” and Elizabeth Olsen will appear in both.

The multiverse in the title is an interesting detail. “Spider-Man: Far From Home” featured the villain Mysterio, who (spoiler) claimed to be from an alternate earth in another dimension. Of course, it turned out that he was actually just an extremely skilled con artist who made the whole thing up.

But the original “Doctor Strange” did actually involve real multiverse elements — Strange had to travel into the Dark Dimension, home of Dormammu, in order to save the earth from destruction. So multidimensional doings are absolutely in his wheelhouse. But we’ll all still have to wait until 2021 to see just how this shakes out.
