What attracted you to doing Dredd?

THIRLBY: I’d always wanted to be an action heroine. That’s a chick dream, getting to wear a leather bodysuit and be blonde and kick ass. But, what really attracted me to Dredd was the script. It was fantastic! It was about people and characters, and not just about explosions and fighting. My character, specifically, was incredibly dynamic and very complex, and goes through a hell of a lot. She has a complete arc in the film, so that’s really what drew me to that.

She’s a prostitute who then kills her pimp and takes over his drug-running business. And Ma-Ma is a bit of a man-hater.I think of her like an old great white shark who is just waiting for someone bigger and stronger to show up and kill her. She’s ready for it. In fact, she can’t wait for it to happen. And yet no one can get the job done. She’s an addict, so she’s dead in that way, but that last knock just hasn’t come. This big, fat, scarred shark moving through the sea and everyone flees and she’s like, 'Will someone just have the balls to do it? Please?'
