"American Horror Story" creator Ryan Murphy warned that the audience may have heart attacks when they watch the upcoming season of the show.

There is no stopping the showrunner from dropping hints that the upcoming season of "American Horror Story" will be the scariest season yet. Murphy first revealed a slew of teasers for the show's fourth season. He also said that Twisty the Clown scares a third of the crew whenever they were shooting the scenes. People with a phobia of clowns should therefore refrain from watching the upcoming episodes of "American Horror Story: Freak Show".

"We said in the writer's room that if we were going to do clowns, we were going to create the most terrifying clown of all time," Murphy told Buzzfeed News. "That was our goal when we were writing him... I'm worried that people are going to have cardiac arrests..."

Throw in Kathy Bates' previous statement that she was unable to sleep at night after she filmed the first episode of the show's new season, and the viewers are cautioned that the show is not for those with a faint heart.

Meanwhile, the premiere of the hit suspense TV show, which will air on Oct. 8, will be entitled "Monsters Among Us" and will feature one of the few surviving freak shows in the country struggling to stay in business, battling with the emergence of new forms of entertainment like television. A bizarre news at a local farmhouse will catch the attention of ringmaster Elsa Mars (Jessica Lange) that could salvage her show.

Based on the title, the first episode will most probably introduce the members of the freak show and will center on Elsa Mars' search for deformed and unique people to join her show. It is still unknown who she will find at the farmhouse, but bets are on that she will stumble upon the conjoined twins Dot and Bette played by Sarah Paulson.
