One of the big surprises at this year's Comic-Con was Dredd.  For those unfamiliar with the film, Dredd is an adaption of the 2000AD comics character Judge Dredd, and it stars Karl Urban, Olivia Thirlby, and Lena Headey.  The film follows Dredd (Urban) and rookie Judge Cassandra Anderson (Thirlby) fighting through a tower that’s crawling with thugs in their attempt to bring down drug overlord Ma-ma (Headey).  Lionsgate premiered the film in San Diego, and it's pretty great.  Unlike a lot of films that get an R rating due to one violent scene, Dredd is borderline NC-17 due to tons of blood and violence.  Trust me, Dredd is going to surprise you and it's definitely worth checking out when it premieres on September 21.Lionsgate has just released a very cool graffiti-style outdoor billboard for the film and they're letting us premiere it online.  If you live in New York City, you might have noticed it when riding the subway.  Hit the jump to check it out, and here's my recent interviews with Karl Urban and Olivia Thirlby.Here's the official synopsis for Dredd:

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 (Karl Urban) 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.
