MCU Phase 4: Every Single Character Confirmed (So Far)

63. Nightmare (TBC) - Doctor Strange In The Multiverse Of Madness

Okay, so maybe CONFIRMED is a bit of an exaggeration at this point, but there's about a 95% chance that Nightmare is in Doctor Strange 2 at this stage. Not only does the mention of "Madness" in the title seemingly allude to the Realm Of Madness - a realm, coincidentally, adjacent to Nightmare's own universe, the Dream Dimension - but he's also apparently been confirmed by writer C. Robert Cargill.

We've known for some time that Scott Derrickson wanted to bring Nightmare to the MCU and a pure horror movie, the writer's confirmation and the tease of the title can't really be pointing to anything else. Now, if they can just get Keanu Reeves to play him...
