Originally named as Madeline Madrigal, the female villain is a vicious gang leader who has flooded Megacity One with the reality-altering drug called Slo-Mo, which automatically puts her at odds with Karl Urban's Judge Dredd.
According to Headey, Ma-Ma will be akin to a great white shark:
“I think of her like an old great white shark who’s just waiting for someone bigger and stronger to show up and kill her,” explains Headey. “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.”
Headey also assures watchers that the reboot will be much darker than the critically panned Sylvester Stallone adaptation released a few decades ago.
“The world [in the film] feels really British,” she says, “and I don’t know if that’s because it’s so dirty and dark. And it’s violent. Just in terms of gunplay, they’re not afraid to show blood and gunshot wounds. And it’s set up in this concrete sort of shanty town - it’s shanty but they’re blocks - concrete favelas.”
Dredd opens in the UK on September 7, 2012.
