Supernatural executive producer Eric Kripke has scored an overall deal at Warner Bros. TV.

According to Variety, in the two-year exclusive pact, Kripke will continue to exec produce and showrun CW's Thursday staple Supernatural, which enters its fourth season this fall.

Kripke also will start to develop new projects under the deal. There's no word if one of the new titles might be a Supernatural spinoff; Kripke has said in the past that he's interested in doing a prequel of sorts that takes place in the Old West and centered on the show's mythology.

Kripke's at work crafting the show's fourth season, following up on the season three cliffhanger that sent Dean (Jensen Ackles) to hell.
