Doctor Strange in the Multiverse of Madness has already made its way on to the Disney+ streaming service, and it came with a bunch of surprises. During the film, we get introduced to classic Marvel comics group, The Illuminati, who in the movie featured Professor Charles Xavier (Patrick Stewart), Captain Carter (Hayley Atwell), Captain Marvel (Lashana Lynch), Black Bolt (Anson Mount), Baron Mordo (Chiwetel Ejiofor) and Reed Richards/Mr. Fantastic (John Krasiniski). The latter of the group has been fan-cast in the role numerous times over the years, so when he arrived on screen it was sure to be viewed as some kind of fan service. As it turns out, Marvel Studios President Kevin Feige was the person that cast Krasnski as Mr. Fantastic and it was because it would make fans dreams come true. Director Sam Raimi revealed as much while doing the audio commentary for the film that can be found via the extra features for the film on Disney+.
