Frequency Casts Supernatural Vet as Imprisoned 'Wily Trickster'

Supernatural angel is taking on a tricky new role.

Curtis Armstrong, who recurred as the celestial being Metatron on the long-running CW series, will guest-star on Frequency, the new CW drama from former Supernatural showrunner Jeremy Carver, TVLine has learned exclusively.

Armstrong will play Karl Pierce, a manipulative and charming former quantum physics professor who’s gone to the dark side. He is described as a wily trickster — but not The Trickster, Supe fans! — who likely went over the edge long ago, but instead wears the mask of an erratic genius. While in prison for murdering his neighbor, he arranges a meeting with Det. Raimy Sullivan (played by Peyton List) after insisting he has important information for her.

Akin to the 2000 Jim Caviezel/Dennis Quaid film of the same name, Frequency explores what happens when List’s character discovers that she is able to speak via ham radio with her estranged detective father (Nashville‘s Riley Smith), who died in 1996. They forge a new relationship while working together on an unresolved murder, but unintended consequences of the “butterfly effect” wreak havoc in the present day.

Armstrong, known for his role as Booger in the Revenge of the Nerds films, has also appeared on the small screen in New Girl, Major Crimes and The Closer.

Frequency premieres Wednesday, Oct. 5 at 9/8c on The CW.
