Aussie Nathaniel Buzolic and Brit Lucien Laviscount have landed the leads in Supernatural: Tribes, the planted Supernatural spinoff, which will air as an episode of the veteran sci-fi series on April 29. The choices blend the CW‘s strategies of casting standout players from its existing series as pilot leads, which is the case with Buzolic, a recurring on The Vampire Diaries and guest star on offshoot The Originals in his role as Kol, the-cwas well as bringing completely new faces, like Laviscount, whose only U.S. credit is an arc on the BBC/Showtime comedy Episodes. Other recent examples include Arrow star Stephen Amell, who first appeared on TVD, and the star of last year’s The Selection pilot, Yael Groblas, who had no previous U.S. credits. Buzolic and Laviscount also continue the trend of overseas actors getting pilot leads this season.

Written by Andrew Dabb and directed by Robert Singer, Supernatural: Tribes is described as a sweeping drama about the various mafia-esque monster families that unknowingly to humans “run” the underbelly of Chicago and who are being tracked by a newly minted Hunter who’s trying to stop them and rid Chicago of anything or anyone supernatural. Buzolic plays David Hayden, a shapeshifter from one of Chicago’s ruling monster families; he has been living as a human, having given up the monster life years ago. Laviscount plays Ennis Roth. When his fiancée is killed in the crossfire of the monster war, the resolute police academy trainee learns the truth about what lurks in the shadows and becomes a monster-hunter himself.
