Trivia: Originally Clair and Chris Redfield were to appear in the film after having been featured in previous movies. But script-changes lead to them being written out, and their fates were left ambiguous. Clair will be re-appearing in the sixth film, however.

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.

Trivia: Emily Blunt signed on to the film after reading the first half of the script. She hadn't even gotten to the scene where her character was introduced.
Trivia: This is Colin Farrell's second role in a movie adopted from a story by Philip K Dick; his first performance was in 2002's Minority Report.
Trivia: Hidden Mickey: One of the red tattoos on Dejah's right arm.
