The rumor which circulated yeterday has now been confirmed, placing the actress in a lead role opposite Karl Urban for the sci-fi, comic book adaptation.
The Playlist have just confirmed with reps for the actress, most notably remembered for her performances in Zack Snyder's 300 and the TV series The Sarah Connor Chronicles, that the British star will play the principle antagonist, Ma-Ma in the project. The antagonist Headey will portray is called Madeline Madrigal, aka Ma-Ma. Here's a brief description of her role in the film, courtesy of Bleeding Cool:
In the Dredd script she’s described as a woman in her late fifties or early sixties with a big scar through her cheek and lip. I can imagine they’ll just ignore the first part of that description, and the only make up Ms. Headey will be subject to will provide the scar tissue but not age her.
Ma-Ma is the leader of a gang who over run the Peach Tree City Block. Almost all of the film takes place here, an extended action sequence not too dissimilar, I guess, to the Die Hard paradigm.
DREDD takes us to the wild streets of Mega City One, the lone oasis of quasi-civilization on Cursed Earth. Judge Dredd (Karl Urban) is the most feared of elite Street Judges, with the power to enforce the law, sentence offenders and execute them on the spot - if necessary. The endlessly inventive mind of writer Alex Garland and the frenetic vision of director Pete Travis bring DREDD to life as a futuristic neo-noir action film that returns the celebrated character to the dark, visceral incarnation from John Wagner and Carlos Ezquerra's revered comic strip.
