If you had trouble figuring out just who this member of the Illuminati was while watching "Multiverse of Madness," we don't blame you. Anson Mount played Black Bolt on ABC's extremely short-lived TV series "Inhumans." It aired for eight episodes in 2017.
Black Bolt is the leader of the Inhumans, a race of genetically modified humans. If that sounds a lot like the X-Men, that was kind of the point. Black Bolt has super strength and stamina, but his biggest power is his "sonic scream," which let him use his voice as an intense weapon. In "Doctor Strange the Multiverse of Madness," Black Bolt's costume is very similar to his comics counterpart's.
It seems unlikely that Marvel is going to try to adapt the Inhumans again, but anything could happen down the road. Nonetheless, it was cool to see Mount reprise his role.
