The second season of Syfy’s “Channel Zero” isn’t premiering until this coming October, but the series has already been renewed for third and fourth seasons. The third season is scheduled to air in 2018 and will be titled “Staircases”.

Brandon Scott (Blair Witch) and Holland Roden (“Teen Wolf”) were the first to join the cast, with Scott playing Officer Luke Vanczyk, a young but already jaded cop, living in the shadow of his father, the Chief of Police. Luke’s world-weary exterior hides a fierce commitment to justice, and a deep love for his troubled community.

Roden will play Zoe Woods, a sharp, tough young woman whose struggles with mental illness have worn her down over the years. She hates that her younger sister, Alice, has to take care of her and she’d give anything to go back to the way things used to be.

Other brief news includes that the fourth season will be based on the “Hidden Door” Creepypasta “I Found a Hidden Door in My Cellar.”

Meanwhile, second season “Channel Zero: No-End House” is inspired by Brian Russell’s Creepypasta, telling the story of a young woman named Margot Sleator, played by Amy Forsyth, who visits the No-End House: a bizarre house of horrors that consists of a series of increasingly disturbing rooms. When she returns home, Margot realizes that everything has changed.

Nick Antosca returns as executive producer, showrunner and writer for the second installment of “Channel Zero,” alongside executive producer Max Landis. Steven Piet directed all six episodes. Harley Peyton (“Twin Peaks”) is writer-co-executive producer, while Don Mancini (“Hannibal”, creator of Child’s Play) also serves as a writer-supervising producer.
