Henry Cavill has confirmed that he will star in the upcoming live-action Warhammer 40,000 television series, which is being written by acclaimed horror director Mike Flanagan. The announcement marks a significant step forward for the long-gestating adaptation of Games Workshop's sprawling sci-fi universe, with Cavill, a well-known fan of the tabletop franchise, attached to both produce and appear on screen.

Details remain scarce, as Cavill has said the character he will play "shall remain a secret for now," giving no indication of who he might portray in the grim darkness of the far future. The project continues to be developed with Flanagan, known for horror works such as The Haunting of Hill House and Doctor Sleep, writing the series, though no release date or further casting has been disclosed.
