Lionsgate has released the first official trailer for Pete Travis’ Dredd, a Alex Garland-penned adaptation of  the U.K. comic-strip Judge Dredd. Set in the dystopian metropolis of Mega City One, the film follows judges Joe Dredd and Cassandra Anderson as they attempt to take down drug dealer Madeline Madrigal.

Dredd stars Karl Urban as Judge Dredd and Olivia Thirlby as Judge Anderson. Lena Headey plays Madrigal (AKA: Ma-Ma). Langley Kirkwood (“Generation Kill”), Joe Vaz (Lost Boys: The Thirst), Scott Sparrow (Death Race 2), and Luke Tyler (Chronicle) round out the cast.
