When asked to describe his favorite part about working on "Doctor Strange in the Multiverse of Madness," screenwriter Michael Waldron's answer was quick. "When the audience groaned when Black Bolt and Reed Richards died on opening night, that was the most rewarding moment for me," he said without hesitation.
The scene, which generated more fan reaction than any other in the multiverse-traversing film, introduces Earth-838's Avengers-equivalent team of heroes — comprising the X-Men's Professor X (Patrick Stewart), Reed Richards/Mister Fantastic of the Fantastic Four (John Krasinski), Captain Carter (Hayley Atwell, in a live-action return to her "What If ...?" role), Captain Marvel (as played by Lashana Lynch), the Inhumans' Black Bolt (Anson Mount) and Sorcerer Supreme Mordo (Chiwetel Ejiofor) — as members of the Illuminati, a brain trust of supes who are dispatched by the Scarlet Witch almost as quickly as they are introduced.
