Russell Mulcahy: This scene here, Allison going into the hospital, is really inspired by De Palma’s “Carrie”.
Jeff Davis: Now, she is walking backwards here.
Russell Mulcahy: Yes, the whole scene is shot in reverse, so she’s walking backwards, all the extras are walking backwards.
Jeff Davis: It gives it such a creepy feel.
Russell Mulcahy: And you’re not quite sure why yet, you just feel uneasy.
Jeff Davis: And these quick flashes of Lydia are definitely inspired by Kubrick and The Shining. Seeing the two girls, the two sisters in the hallway. And I remember being in the editing room and when she touches the window…BOOM…the sound comes back.
