Background & Development
Rumours of an American Horror Story spin off surfaced in 2014 after the conclusion of Coven, however these plans developed into Scream Queens, which premiered in 2015.

After Sarah Paulson's performance in American Horror Story: Hotel and her critically acclaimed portrayal of Marcia Clark in The People v OJ Simpson, FOX Broadcasting approached Ryan Murphy to produce a new series specifically for her. He worked closely with her to develop the idea of The Warrens, originally titled The Ghosthunting Couple. The Show was delayed a year due to the release of The Conjuring 2, which followed a similar premise. Paulson was delighted when Lorraine Warren gave the series a blessing, the clairvoyant came on board as a producer.

After the conclusion of season 6 of American Horror Story, it was confirmed that Sarah Paulson would not return as a regular for the seventh season in order to focus on The Warrens, but an early episode of the next season would serve as a backdoor pilot for the new series.
