Here’s where things begin to get really interesting. As Chiwetel Ejiofor’s Mordo—last seen at the end of the first Doctor Strange absorbing the magical power of others—explains Strange’s destruction of reality, we see Strange placed into a set of tech-y handcuffs and walked by a set of robots (similar to the Ultron Sentries from Age of Ultron) into some sort of chamber wherein we hear, and slightly see, none other than . . .

. . . Sir Patrick Stewart. Give it up for the MCU debut of Professor Charles Xavier—or some version of Professor X at least. Fox once held the rights to the X-Men series, but with Disney’s acquisition of Fox back in 2019, the franchise is back in the hands of Marvel Studios. The X-Men franchise will undoubtedly have its own set of movies at some point in the future. Still, the inclusion of Stewart in Multiverse of Madness feels like a nice treat in the interim.
But that’s not all: The gathered chamber likely means audiences will get to see some version of the Illuminati. In the comics, the Illuminati is a secret society of the best and brightest minds intended to function as a superhero United Nations. The initial set of founding members included Tony Stark, Reed Richards, Doctor Strange, Professor Xavier, Black Bolt, Namor, and Black Panther. For a few different reasons, we won’t see the exact group form in Multiverse of Madness. However, a new Multiversal Illuminati could be a great place to slot in a handful of cameos alongside Stewart. Might we see Hayley Atwell’s Captain Carter variant from the Disney+ animated series What If? A new poster released alongside this trailer contains a tease of her shield, so she’s probably a safe bet. Another possible clue in the poster includes a figure that looks an awful lot like Ryan Reynolds’ Deadpool. With Sir Patrick returning, the likelihood of some other old Marvel actors also returning to reprise their roles is a strong possibility, as there are a handful of seats in that council room.
