Shawn Ashmore has joined the cast of Fox's serial killer drama pilot.
The project - from The Vampire Diaries co-creator Kevin Williamson - will star Kevin Bacon as Ryan Hardy, a retired FBI profiler.
Hardy returns to work when the murderous Joe Carroll (James Purefoy) uses technology to create a cult of fellow serial killers.
X-Men star Ashmore will play a junior FBI agent who assists Bacon's character, according to Deadline.
Valorie Curry will also appear in the pilot as an unwitting young nanny who cares for Carroll's son.
Ashmore's recent credits include a guest role on Fringe, while Curry starred in Veronica Mars and will appear in the forthcoming The Twilight Saga: Breaking Dawn - Part 2.
The Vampire Diaries director Marcos Siega will helm the currently-untitled pilot, which will be produced by Warner Bros TV and Williamson's studio-based Outerbanks Entertainment.
Other drama projects in the works at Fox include a teen spy series from The Playboy Club's Karyn Usher, legal drama Guilty and Josh Friedman's action drama The Asset.
