Just ahead of the premiere of American Horror Story’s fourth season, FX announced plans for a companion anthology series called American Crime Story. The first season will center on the ultimate American crime story - O.J. Simpson.

AHS co-creator Ryan Murphy (Glee, The Normal Heart) will direct from a script by Ed Wood writers Scott Alexander and Larry Karaszewski. It will be based on Jeffrey Toobin’s book The Run of His Life: The People v. O.J. Simpson.

“Time and time again, Ryan Murphy has transformed the medium of television by redefining genres and formats as he did with Nip/Tuck, Glee and the American Horror Story franchise, and we expect the same of American Crime Story,” FX CEO John Landgraf said in a statement. “Scott and Larry have adapted Jeffrey Toobin’s book into a masterful 10-hour piece. I have no doubt that Ryan and his partners, Nina Jacobson, Brad Simpson, Brad Falchuk, and Dante Di Loreto are going to make something very memorable here – and that it will be a spectacular first entry in what is destined to become a series of great true crime-based miniseries.”

The executive producers for the first season of ACS are Murphy; Nina Jacobson and Brad Simpson (The Hunger Games); and Murphy’s frequent collaborator Brad Falchuk. Alexander and Karaszewski will also serve as EPs and are penning the first two episodes. It will be a FXP and Fox 21 production. Production starts in early 2015 in Los Angeles.

AHS: Freak Show starts on Wednesday.
