Lionsgate has released the official trailer for Dredd, a second attempt at a movie adaptation of the popular British comic book series. (The original, 1995's Judge Dredd, starred Sylvester Stallone as the title character. The less said about the film the better.) The upcoming 3D reboot has Karl Urban taking on the role of the futuristic lawman, whose charter is to protect Mega-City One, a dystopian urban wasteland caught in the grip of a rampant drug epidemic. Along with a rookie with psychic abilities (Olivia Thirlby), Dredd must take on a 200-story vertical slum controlled by a prostitute turned drug lord called Ma-Ma (Lena Headley), who's declared war on the Judges. Directed by Peter Travers, Dredd is scheduled to open in theaters September 21st.
