In Neon Demon, she plays a cool ringleader that other girls want to follow. Envious, emotionally unstable and a tad delusional, she shows her true maniacal colors in the end. After first creeping Jesse out by sucking the blood out of her wound, she ends up killing and later eating Jesse to absorb her virginal youth and beauty.
I do not know if Elle Fanning is Jesse or not. But does this sucking of blood from a wound only to later eat this person named Jesse make Abby Lee the demon? Time will tell.
Abbey Lee is The Dag in the upcoming road movie Mad Max Fury Road. She is the one who looks like she is about to do the Kids in the Hall squish your head bit in the Comic-Con trailer. She also has a part in Alex Proyas' Gods of Egypt, which is currently in post and due out a year from now.
