There are unconfirmed reports that the currently filming 3D ‘Dredd’ has just added actress Lena Headey as the major villain for the film.

Headey (‘Terminator: The Sarah Connor Chronicles’, ‘300’, ‘Game of Thrones’) will join lead Karl Urban (‘Star Trek’, ‘The Chronicles of Riddick’, ‘Red’, ‘Priest’) for what will hopefully be a closer representation of the gritty UK comic book ‘Judge Dredd’ than the 1995 Sylvester Stallone film version.

Headey will play the main villian and gang-leader, Madeline Madrigal AKA Ma-Ma.

The cast includes: Olivia Thirlby (‘Bored to Death’, ‘Juno’), Jason Cope (‘District 9’, ‘Doomsday’), and Warrick Grier (‘The Prisoner’, ‘Death Race 2’).

‘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 movie has a December 1, 2011 UK release date.
