Trivia: Dredd's face is never shown during the film. This is consistent with the comic strips in which Dredd is almost never shown without his helmet and, on the rare occasions when he is, his face is obscured in some other way. Fans were critical of the 1995 Judge Dredd film for the fact that Dredd spent much of the time with his helmet off and his face exposed.
Trivia: Director Pete Travis had a hard time on the set of Dredd - Karl Urban would not take his direction, only that of the film's writer Alex Garland. During editing, Travis was blocked out of the process due to conflicts between the producers and the executives, with Garland taking over. Garland briefly attempted to gain a co-director credit due to overseeing the editing, but was blocked by the Director's Guild of Great Britain, because he had not overseen filming or even directed before. Travis and Garland then reached an agreement where Garland would only get writing and producing credits. Several crew members, including Karl Urban, still consider Garland the primary director. Urban said in an interview "what a lot of people don’t realize is that Alex Garland actually directed that movie...I just hope when people think of Alex Garland’s filmography that Dredd is the first film that he made before Ex Machina."
Trivia: During the scene at the theater, after Anderson is taken hostage and encounters Ma-Ma, there's a movie poster for "Krysler's Mark" with the tagline "A Quest for a child." Owen Krysler's is a character in the Judge Dredd comics. He's a mutant and child Judge. The poster shows it's "Directed by Ulf Suhrmuller." Suhrmuller was in the art department for "Dredd" as an art runner and model maker.
Trivia: Karl Urban did all of his own motorcycle stunts.
Trivia: The movie explains that Mega City One has a population of 800 million people and 17,000 serious crimes are reported daily, which works out to about 6.2 million per year. The current US population is roughly 331 million people, and over 9 million crimes are reported every year, which works out to nearly 25,000 per day. This actually means that Mega City One is significantly safer than the present day United States when it comes to the crime rate.
Answer: Kay wanted to punish her for what she did to him earlier. Ma-Ma wanted leverage against Dredd should he get past her Judges.
