Shadowhunters has found its rogue villain. Coming off his stint as King Henry II on Reign, Alan Van Sprang has been cast as a recurring guest star in ABC Family’s straight-to-series drama Shadowhunters.

Based on the best-selling young-adult fantasy book series The Mortal Instruments by Cassandra Clare, Shadowhunters follows 18-year-old Clary (Katherine McNamara) who finds out on her birthday that she is not who she thinks she is but rather comes from a long line of Shadowhunters — human-angel hybrids who hunt down demons. When her mother Jocelyn is kidnapped, Clary is thrown into the world of demon hunting with mysterious Shadowhunter Jace (Dominic Sherwood) and her best friend Simon (Alberto Rosende). Now living among faeries, warlocks, vampires and werewolves, Clary begins a journey of self-discovery as she learns more about her past and what her future may hold. Cast also includes Emeraude Toubia, Matthew Daddario and Isaiah Mustafa.

Van Sprang, repped by APA and the Arc in Canada, will play Valentine, a mysterious Shadowhunter wielding immense power. His stoic, charming, and confident presence allows him control over his many followers. To seek out what he wants, Valentine executes anyone in his way, never thinking twice about it.

Shadowhunters is produced by Constantin Film and executive produced by Ed Decter and McG. McG will also direct the first episode.
