The upcoming “Monarch: Legacy of Monsters” prequel on Apple TV has added three new members to the cast.

Variety has confirmed that Corey Stoll (“Imperfect Women,” “Appropriate,” “Billions”), Ralph Inneson (“The Witch,” “The Fantastic Four: First Steps”) and Nyasha Hatendi (“Agatha Christie’s The Seven Dials,” “Casual”) will appear in the new series, which was originally announced in December 2025.

They join series star Wyatt Russell, who will once again play Lee Shaw, as well as Millie Brady and Pilou Asbaek. The exact character details of those besides Shaw are being kept under wraps.

Stoll is represented by Suskin/Karshan Management, UTA and SRDA Law. Ineson is represented by Gordon, French and Gersh. Hatendi is represented by The Artists Partnership, Principal Entertainment, Granderson Des Rochers and Gingham PR.

The show’s tagline reads: “The series will follow the story of Colonel Lee Shaw (Russell), an American agent who in 1984 undertook a secret mission behind enemy lines in an attempt to prevent the Soviets from releasing a horrifying new Titan large enough to destroy the United States and turn the tide of the Cold War.”

Joby Harold writes, produces and executes the show through Safehouse Pictures. Harold currently has an overall deal with series producer Legendary Entertainment and is developing multiple Monsterverse shows. Safehouse’s Tory Tunnell also executive produces alongside Russell, Andy Goddard, Kyle Bradstreet, Jim Skotchdopole, Max Borenstein, Chris Black and Alex Boden. JD Dillard will serve as director and executive producer. Hiro Matsuoka and Takemasa Arita are executive producers on behalf of Toho Co., Ltd., the owner of the Godzilla character. Toho licensed the rights to “Monarch: Legacy of Monsters” from Legendary.

The castings were first reported by Deadline.
