Dredd is set for September 21st, 2012 release.
Dredd takes place on a fictional Earth created as a result of the Atomic Wars. Survivors of this period are living in Mega-Cities, which protects its citizens from the Cursed Earth, a radioactive desert environment populated by mutants. The main story takes place in Mega-City One, where the police who are now called judges have the power to use police brutality to some extent to fight extreme murders. One man, Judge Dredd (Karl Urban), a senior law enforcement officer, teams up with a cadet called Judge Anderson (Olivia Thirlby) to track down a terrorist organization lead by Ma-Ma (Lena Headey), who is responsible for selling a reality-altering drug called Slo-Mo.
