Dredd

Dredd is a 2012 live-action movie based on the Judge Dredd comic. Stars Karl Urban as Dredd. The movie opens with Dredd pursuing a van of criminals and finding that they're users of the "Slo-Mo" narcotic (which causes users to experience time at a slower pace). He and rookie Judge Anderson go to the Peachtree block to take out the manufacturers, and matters escalate from there.

Very different from the other Judge Dredd movie.

 * Abnormal Ammo: As with the original, Dredd makes use of a "hot-shot" round to roast a criminal without harming the hostage he'd taken, and a flare round to take out a whole floor full of criminals at once.
 * Cool Helmet: Part of the Judges' standard uniform. Unlike the other Judge Dredd movie, Dredd keeps his helmet on at all times.  (In fact, this was a promise made to fans by one of the writers during production!)  Anderson loses hers, and explains that she often goes without it as it interferes with her psychic powers.  Here's what Dredd has to say about that:
