Despite the recent cancellation of Marvel's Inhumans, Black Bolt and the Royal Family could still have a future in the Marvel Cinematic Universe. Marvel TV head Jeph Loeb says he believes Inhumans was "a fun show" and is hopeful that the characters will live on in future MCU TV shows.
Inhumans, which was at one point slated to be a film in Phase 3 of the MCU, was given an eight-episode season order at ABC. Unfortunately, the series was highly criticized long before it even premiered. Inhumans received low ratings and poor reviews, causing many to consider it as a major failure for Marvel TV. Several months after the end of the first season, Inhumans was officially cancelled by ABC in May.
During a Reddit AMA to promote Freeform's Cloak & Dagger, a fan asked Jeph Loeb if the actors who portrayed the Inhumans could be brought back for future TV shows or movies set within the MCU. Loeb expressed hope for the idea and praised the cast.
Hope so. Great cast and for what's it worth, still think is a fun show.
There's no question that Inhumans was a disappointment for Marvel. Late night talk show host Jimmy Kimmel and one of Marvel's own comic book titles, Deadpool, have made jokes at the show's expense. Some are hoping that the MCU will move on from the series by ignoring it. However, not all fans share such low opinions of the show. The series has developed a loyal fan following which launched a petition for ABC to renew the series.
Though the effort ultimately proved unsuccessful, there remains a sizable number of fans who would love to see Black Bolt, Medusa, Crystal, Lockjaw, and the others find a new home. The Inhumans could fit into the MCU similar to the way they exist in the comic books. The Inhumans are occasionally given their own stories, but most are either limited series or short-lived titles. The Inhumans are generally used as guest stars, which could be the best way for them to work in the MCU as well.
Due to the deep connectivity that exists within the MCU, a future for the Inhumans certainly isn't out of the realm of possibility. After all, it was season 2 of Agents of S.H.I.E.L.D. that set the stage for the Inhumans' introduction, making S.H.I.E.L.D. the most likely current option for fans to see more of the Royal Family.
