In the new issue of Empire Magazine dedicated to the film, producer Richie Palmer commented on the rumors about the presence of the Illuminati, a team of sublime minds from the Marvel universe who secretly gathered to make the most difficult decisions regarding the future of the Earth.
Without confirming anything, Palmer declared: "I will say that I love the Illuminati. But if we ever introduce the Illuminati in the future, it might be more MCU-driven and have some more ties to our characters in the MCU, versus just replicating what's in the comics."

Despite this statement, the same Empire Magazine seems to have definitively confirmed the rumors itself by showing a photo of Doctor Strange and pointing out that he stood right before the Illuminati in the same scene shown in the trailer where he met Charles Xavier.

Given that this is a key number for the film's promotional campaign as it includes the first details and statements from the creative team, this is hardly a mistake as it must be verified by Disney before it can be released.
As mentioned above, Doctor Strange in the Multiverse of Madness, written by Michael Waldron and directed by Sam Raimi, will arrive in theaters on May 6, 2022. The cast of the movie includes Benedict Cumberbatch (Stephen Strange / Doctor Strange), Elizabeth Olsen (Wanda Maximoff / Scarlet Witch), Chiwetel Ejiofor (Karl Mordo), Benedict Wong (Wong), Rachel McAdams (Christine Palmer), Xochitl Gomez (America Chavez) and Adam Hugill (Rintrah).
