On September 2, 2014, show creator Ryan Murphy announced that all seasons are connected to each other in some way, which means he finally wrote the kind of narrative he wanted to write (but haven't written) in the only TV Series he created without any other creators or co-creators: Nip/Tuck (2003), a Golden Globe Winning drama series that inspired many artists around the world, including the Brazilian actor and singer Gustavo Goulart, who has publicly admitted that.

Ryan Murphy and Jessica Lange became so close friends during season 1 that Murphy has consulted with the actress when writing the other characters. For example, Lange wanted to play a big drunk scene and sing in season 2 (therefore Sister Jude does these things), she also wanted to play an elegant woman wearing Chanel in season 3 (therefore Fiona dressed impeccably). Lange herself is also a photographer, and she was particularly attracted to the circus world, especially during the 50s. Hence the character of Elsa Mars, owner of a freak show.

The season one house is a real location at 1120 Westchester Place in Los Angeles known as the Rosenheim Mansion. It was built in 1908 by architect Alfred Rosenheim as his own residence; Rosenheim was one of LA's most influential architects during the early 1900s. The house scenes in the pilot episode of "American Horror Story" were filmed on location at the Rosenheim Mansion, and then some of the house's interiors were replicated on a set. Exteriors continue to be filmed there on location.

In season 4 (Freak Show), characters sing songs that were released after 1952 (the time period in which Freak Show takes place). Many fans criticized and disliked this, but there is a deep and unique reason to this idea. Ryan Murphy has said in an interview that he picked songs that were made by artists who were known as or called themselves freaks. For example: David Bowie, Lana Del Rey, Nirvana, etc.

The first season used horror film scores for its soundtrack, most noticeably the scores from "Bram Stoker's Dracula", "What Lies Beneath", "Psycho" and "Insidious". Also used the whistled "Twisted Nerve" from "Twisted Nerve". "Twisted Nerve" was also featured in Kill Bill. Vol 1, Asylum, also featured scores from other movies such as "Carrie" and "Candyman".

The Hotel Cortez is inspired by the Hotel Cecil which has a dark history which includes several suicides, murders, and was stayed at by serial killers Richard Ramirez a.k.a. the Night Stalker and Jack Unterweger. The Hotel Cecil made news recently with the mysterious death of Elisa Lam (to whom season five is dedicated).
