While it didn't set any box office records, Dredd 3D was an absolute joy to watch--fun and action-packed with moments of humor, humanity and, of course, ultra-violence, it was easily one of the best comic book movies in a year full of them, and done for pennies on the dollar compared to the big Marvel and DC films.
A big part of the film's appeal was the gritty, visceral look of Mega City One, where Dredd makes his home. A new feature from the Blu-ray, featured below via the IGN YouTube page, gives a sense for how they got that feeling.
Check it out. Dredd is on DVD, Blu-ray and video on demand January 8.
