Joker came to be out of director Todd Phillips’s brain, intending to be a more grounded comic book film. A DC “black” label film, Joker is outside the normal bounds of the DC film universe. This film has no connection to Shazam, or Man Of Steel, or Justice League. It still is a DC film, but it is a one-off, with currently no intent to continue the usage of any character brought to life in this movie. Joker was intended to move beyond the current idea of a comic book film, and create something new. And in that aspect, it succeeds, with very few references to the Batman-centric universe the Joker character comes from. Phillips intentionally left the character ambiguous. Is Joker the batman Joker? Or is he someone new?
