While Hulu, which is owned by Fox (and by proxy also Disney), announced that it would be expanded its partnership with Marvel Television with two new live-action series, “Marvel’s Ghost Rider” and “Marvel’s Helstrom”, the former was put on ice. Thankfully, “Helstrom” is moving forward and has just been cast up.

Daimon and Ana Helstrom are the son and daughter of a mysterious and powerful serial killer in Marvel’s Helstrom.

The siblings have a complicated dynamic as they track down the terrorizing worst of humanity — each with their attitude and skills. 

Tom Austen (“Grantchester,” “The Borgias”), pictured above, stars as the aforementioned Daimon Helstrom, a professor of ethics who moonlights as an exorcist. Daimon has no illusions about saving a world he has no patience for; he just hopes he can help a few of the people closest to him. In his battle against a hidden world, Daimon is determined to root out demons as they arise, and will not stop until they’re vanquished.

Sydney Lemmon (pictured in “Fear of The Walking Dead”) was just cast as Ana Helstrom. By day, Ana runs a successful auction house and suffers no fools, but her true interest lies in hunting down those who hurt others. Traumatized by her father as a child, Ana is driven to rid the world of those like him, even as she secretly worries her father will return.
