Dredd is a 2012 science fiction action film directed by Pete Travis and written and produced by Alex Garland. It is based on the 2000 AD comic strip Judge Dredd and its eponymous character created by John Wagner and Carlos Ezquerra. Karl Urban stars as Judge Dredd, a law enforcer given the power of judge, jury and executioner in a vast, dystopian metropolis called Mega-City One that lies in a post-apocalyptic wasteland. Dredd and his inexperienced partner, Judge Anderson (Olivia Thirlby), are forced to bring order to a 200-storey high-rise block of flats and deal with its resident drug lord, Ma-Ma (Lena Headey).
The future America is an irradiated waste land. On its East Coast, running from Boston to Washington DC, lies Mega City One - a vast, violent metropolis where criminals rule the chaotic streets. The only force of order lies with the urban cops called "Judges" who possess the combined powers of judge, jury and instant executioner. Known and feared throughout the city, Dredd is the ultimate Judge, challenged with ridding the city of its latest scourge - a dangerous drug epidemic that has users of "Slo-Mo" experiencing reality at a fraction of its normal speed. During a routine day on the job, Dredd is assigned to train and evaluate Cassandra Anderson, a rookie with powerful psychic abilities thanks to a genetic mutation. A heinous crime calls them to a neighborhood where fellow Judges rarely dare to venture - a 200 storey vertical slum controlled by prostitute turned drug lord Ma-Ma and her ruthless clan. When they capture one of the clan's inner circle, Ma-Ma overtakes the compound's control center and wages a dirty, vicious war against the Judges that proves she will stop at nothing to protect her empire. With the body count climbing and no way out, Dredd and Anderson must confront the odds and engage in the relentless battle for their survival.
