Yesterday, American Horror Story creator Ryan Murphy announced the title and premise of season 4. Freak Show. A spokesman for 20th Century Fox confirmed the show will be set in Jupiter, Florida.
Though nothing has been confirmed regarding the series filming on location in Jupiter, last season's Coven was shot in New Orleans, so chances are Murphy and his film crew could be taking over South Florida.
The year will be 1950 and the premise a carnival theme with Jessica Lange returning to play a German expatriate managing a fading "freak show." Most of the other stars from season 3's "Coven" will be returning.
