The Aussie star, who made her name as a teen opposite Jim Carrey in Lemony Snicket's a Series of Unfortunate Events, will play the dosing princess in a new indie movie - and she admits it's a racy role that will shock many film fans.
The actress tells Nylon magazine, "She (character) falls into this bizarre area of prostitution, where she is willingly drugged. It's very, very heavy.
"I did it straight after (new film) Sucker Punch, which was such a positive experience that I was feeling completely confident and ready to do anything.
"I remember I was nervous before the first nude scene, and then as soon as the camera's on, you're in another place - it's not scary.
"It's not where I'm like, 'Oh my God, everybody's gonna see my a**'."
