It was announced last week that the popular CW show Supernatural might be getting a spin-off.  Huffington Post reveals new details.

Executive producers Jeremy Carver and Robert Singer told Entertainment Weekly earlier this week that the Supernatural spin-off is currently scheduled to be introduced to viewers as Season 9, Episode 20. Carver told EW that if the CW picks it up, the show will “explore the clashing monster and human characters,” and “have main characters who are both human and monsters.” That will include,“families of monsters and families of hunters,” Singer added, pointing out that the spin-off is “much more of an ensemble than Supernatural.”

The CW president Mark Pedowitz said the Supernatural spin-off would be set in Chicago and focus more on the urban aspect of hunting instead of the back roads.

Though Pedowitz said that he didn’t think there are “any plans for [regular] characters on Supernatural” to be on the spin-off, the Executive Producers told EW that the show’s stars Jared Padelecki and Jensen Ackles will be a part of the Chicago-set spin-off. “Most spin-offs, you spin characters out and create a show about them. Jared and Jensen will be in the spin-off, but it’s an entirely different cast of characters,” says Singer.

Regarding Supernatural, the CW’s current longest-running series, Pedowitz said he sees the show continuing to a Season 10 and perhaps beyond. “I would love Supernatural to continue for as long as they can continue, as long as they have great stories to tell,” Pedowitz said at the TCAs. “From what I’ve read, Jeremy Carver is writing arcs that could go longer. As long as fans are there and ratings are there, there’s no reason it couldn’t continue … If they can still tell great stories and Jared and Jensen still want to do it, why wouldn’t you continue?”

Supernatural Season 9 premieres Tuesday, October 8 at 9 p.m. ET on The CW.
