The film is set for release in the UK on 7 September 2012 and in the USA on 21 September. Karl Urban stars as Judge Dredd and Olivia Thirlby as Psi-Division Judge Anderson, with Lena Headey as the main villain, Madeline Madrigal (aka 'Ma-Ma'). The film was shot in South Africa with a budget of $45 million. It'll be in 3D (grumble) and has been R-rated in the United States.
First impressions: looks reasonable (backed up by some solid early reviews). Thirlby, Urban and Headey all look good, the costumes and sets look decent and the whole thing certainly looks more promising than the disappointing 1995 Stallone movie. However, the depiction of Mega-City One looks dull. The Stallone movie did have an impactful visual style that worked very well. This version looks fairly generic in comparison.
Before anyone asks, yes, Dredd keeps his helmet on for the duration.
