The actress listened to punk icons Lou Reed and the Misfits and even took bass lessons in preparation for her role as musician Annabel in the spooky hit movie.
Now she has revealed her real-life rocker muse was Canadian star Glass, admitting she even copied the singer's jet-black bob hairstyle.
She tells MTV, ""It's on the page (in the script) that Annabel plays punk, and she plays bass in a punk band. She's not like (The Girl With The Dragon Tattoo character) Lisbeth Salander. She's not hardcore, full-on. She's like the girl who went to community college, hangs out with her friends, loves punk music, and plays bass. She'll never be famous. She's not incredibly good at it.
""Talking to the director (Andres Muschietti) we talked about (my) look for that. He sent me pictures of Alice Glass. I thought, 'Oh, my God. She's so rad (cool). That's a great idea for the character.' So that's where we started with the hair, thinking Alice Glass.""
