Supernatural showrunner Jeremy Carver, whose drama pilot Frequency was picked up to series by the CW, is moving to the new series as showrunner. Supernatural executive producers Robert Singer and Andrew Dabb will taking over the helm for the series’ upcoming Season 12 as new showrunners.

Supernatural Season 11Singer has served an executive producer/director and occasional writer on Supernatural since the first season. Dabb signed on in Season 4 as writer/story editor, rising to co-executive producer. Carver has been showrunner of Supernatural since Season 8 after joining the series as a writer in Season 3. He left at the end of Season 5 to work on Being Human at Syfy and returned to Supernatural in Season 8 to assume showrunner duties.

Carver’s Frequency series is a reimagining of the 2000 New Line Cinema film. It centers on a female police detective in 2016 who discovers she is able to speak via a ham radio with her estranged father (also a detective), who died in 1996. They forge a new relationship while working together on an unresolved murder case, but unintended consequences of the “butterfly effect” wreak havoc in the present day. Carver is writer and executive producer.

Singer and Dabb’s promotion was first reported by TVLine.
