American Horror Story: Murder House

The first season of American Horror Story, retroactively subtitled Murder House, centers on the Harmon family, who, after dealing with a miscarriage and infidelity, move to a restored mansion in Los Angeles, unaware that the ghosts of its former residents and their victims haunt the house. The ensemble cast includes Connie Britton, Dylan McDermott, Evan Peters, Taissa Farmiga, Denis O'Hare, and Jessica Lange.

Created by Ryan Murphy and Brad Falchuk for the cable network FX, American Horror Story was announced in February 2011, with production commencing that April. The season was broadcast between October 5 and December 21, 2011, being produced by 20th Century Fox Television. Dante Di Loreto served as executive producer alongside Murphy and Falchuk.

Murder House generally received positive reviews from critics and drew consistently high ratings for FX, ending its cycle as the biggest new cable series of the year. The season was nominated for various industry awards, including the Golden Globe Award for Best Television Series – Drama, and received a total of seventeen Emmy Award nominations. In addition, Lange won the Golden Globe, the Screen Actors Guild Award, and the Primetime Emmy Award for her supporting role.

What you saw in the finale was the end of the Harmon house. The second season of the show will be a brand-new home or building to haunt. Just like this year every season of this show will have a beginning, middle and end. [The second season] won't be in L.A. It will obviously be in America, but in a completely different locale.

Creators Murphy and Falchuk began working on American Horror Story before their Fox series Glee began production. Murphy wanted to do the opposite of what he had done previously and thus began his work on the series. He stated, "I went from Nip/Tuck to Glee, so it made sense that I wanted to do something challenging and dark. And I always had loved, as Brad had, the horror genre. So it just was a natural for me." Falchuk was intrigued by the idea of putting a different angle on the horror genre, stating that their main goal in creating the series was to scare viewers. "You want people to be a little bit off balance afterward," he said.

The dark tone of the series is modeled after the ABC soap opera Dark Shadows, which Murphy's grandmother forced him to watch when he was younger to toughen him up. He also cited Rosemary's Baby, Don't Look Now, The Amityville Horror, and Stanley Kubrick's version of The Shining as influences for the series.

Murphy and Falchuk planned that each season of the series would tell a different story from the beginning. After the first-season finale aired, Murphy spoke of his plans to change the cast and location for the second season, while retaining some actors from the first: "The people that are coming back will be playing completely different characters, creatures, monsters, etc. [The Harmons'] stories are done."

In February 2011, FX officially announced that it had ordered a pilot for a possible series from Ryan Murphy and Brad Falchuk, with both Murphy and Falchuk writing and Murphy directing. Dante Di Loreto was announced as executive producer. Production on the series began in April 2011. In July 2011, FX officially announced the project had been given a series order consisting of 13 episodes. In August 2011, it was announced that Tim Minear, Jennifer Salt, James Wong, and Jessica Sharzer had joined the series as writers.
