In between these two "Bucket Of Blood" cues is another Donaggio cue from Carrie: "For The Last Time We'll Pray" plays as Lana makes her way inside the asylum for the first time. Sister Mary (Lily Rabe) leads Lana up the stairs to meet Sister Jude, and they walk in on her just as she is beginning to shave the head of a patient, Shelly (Chloe Sevigny).

Now before I get to the third use of "Bucket Of Blood," which comes later on in the episode (confirming the running motif), it is worth noting that Sevigny portrayed Grace Collier, the journalist, in Douglas Buck's 2006 remake of De Palma's Sisters. This, of course, is the journalist character who was played by Jennifer Salt in De Palma's Sisters. Salt is an executive producer on American Horror Story, and she wrote a couple of episodes from the first season. This current episode, and, it would appear, the season to come, has clear echoes of De Palma's Sisters, in which Grace, investigating a murder, infiltrates a mental health clinic. However, Grace is discovered and captured by Dr. Emil Breton (William Finley), who tricks the others at the clinic into thinking Grace is a stray patient. "You want to know our secrets," Emil says to Grace as he puts her under a hallucinatory sedation. "We will share them with you. Watch." On American Horror Story, Lana is eventually discovered and captured in a similar manner. "She wanted an inside look into our facility," Sister Jude later tells Lana's roomate, "and I will see that she gets it."

But before that happens, "Bucket Of Blood" is heard a third time as Sister Mary appears to be feeding someone or something in the woods, and the music this time crescendos as Lana herself startles Sister Mary-- bringing Lana's appropriated Donaggio motif full circle.

Appropriating themes from horror movies is nothing new for American Horror Story. Last season, Bernard Herrmann's whistling theme from Twisted Nerve was used as a recurring theme for Evan Peters' character. (That same theme had previously been reappropriated by Quentin Tarantino for a memorable De Palma-Dressed-To-Kill-esque split screen sequence in Kill Bill Vol. 1.) For all I know, there were other such music cues that I did not recognize. But I wouldn't be surprised to hear "Bucket Of Blood" again throughout the season, if Lana's story continues.

"An admirer of Bretchian distanciation who likes to keep the viewers aware of their emotional involvement in the film, De Palma values the medium of film first and foremost. 'You suck them in and annihilate them. Then you say, “It's just a movie, right? It's not real,”' he noted in an interview.

"He reached a wider audience with Carrie, the film adaptation of Stephen King´s horror novel, which garnered the actors Oscar nominations for their performances. In it, Brian De Palma made extensive use of split-screen and slow motion shots to tell the story visually rather than through dialogue. His film, The Fury, made an impression on Godard, who included De Palma in his project Histoire(s) du Cinéma."
