Doctor Strange isn't an Avenger, he's outside of that realm: Benedict

Benedict Cumberbatch has said that Doctor Strange isn't an Avenger. "I'm not at Stark Tower with Nick Fury. No, he's sort of outside of that realm," Benedict added. He stated Doctor Strange is there to protect the reality of the Avengers in a different way. 'Doctor Strange in the Multiverse of Madness' is expected to have cameos by MCU characters.
