The first full trailer of Doctor Strange in the Multiverse of Madness arrived during last night's Super Bowl LVI between the Los Angeles Rams and the Cincinnati Bengals, and there is a lot to unpack. Is that Sir Patrick Stewart's Professor Charles Xavier's voice in the trailer? Does that mean that the X-Men are finally joining the Marvel Cinematic Universe, or is it another Ralph Bohner (Evan Peters) situation?

Let's start with the big question. Yes, it sounds like Sir Patrick Stewart's voice in the trailer, as the man speaking has a British accent. The moment leaves the taste of a Spider-Man pointing meme in the viewer's mouth and harkens back to one of the best cross-overs in history. As Mi Capitán Jean-Luc Picard comments about Professor Charles Xavier on the holodeck in the novel Star Trek: The Next Generation/X-Men: Planet X by Michael Jane Friedman (how's that's for a multiverse of madness?), "As the doctor had warned him, he and the professor bore a passing resemblance to one another."

If this is true, Professor X would be the first major X-Men character to appear in the MCU. Obviously, it wouldn't be the identical Professor X whose body was exploded, then brain jumped into the body of a brain-dead comatose man in X-Men: Days of Future Past, or the Charles Xavier that was killed by X-24, and then buried in an unmarked grave in Logan. It probably won't even be the Charles Xavier seen in FX's Legion, who battled and defeated Amahl Farouk on the Astral Plane.

Will It Be a Crisis on Infinite Professor X's?

However, it could be the version of the Xavier seen in Legion on FX.

In Legion, a third-season flashback episode showed us a glimpse of Xavier as a British soldier during World War II. At some point after the war, the young Xavier was committed to a mental health institution where he met his ex-wife and David Haller's mother, a Romani survivor of the Holocaust. In Legion, when David Haller travels back in time, Xavier was warned of the threat that Farouk posed, and instead of going into battle, he worked with a future version of Farouk to convince David and the past Farouk to make peace and accept a changed timeline.

But what do those changes mean for Stewart's Professor X? Has he joined the Illuminati? The Illuminati's first published appearance is in 2005's New Avengers #7 written by Brian Michael Bendis. Their history was discussed in the special New Avengers: Illuminati (May 2006). This secret organization is formed of some of the most brilliant and powerful minds in the Marvel Comics universe, with a roster that also includes Namor the Sub-Mariner, King T'Challa of Wakanda, Tony Stark, Reed Richards, Black Bolt, and of course, Doctor Stephen Strange.

Rumors have long been circulating about the introduction of both Namor and Mr. Fantastic into the Marvel Cinematic Universe, and the Illuminati could provide an avenue for just that... although it's possible that the Stark in question could be a rumored variant played by Tom Cruise, leading to the possibility that the casting we see for the Illuminati members in Multiverse of Madness might not be the same actors who appear in the roles in subsequent MCU appearances by the characters.
