Batman: The Killing Joke (2016, dir. Sam Liu)

An origin story for The Joker, filtered through his attempts to show anyone can become like him if they have a single day traumatic enough. Okay expansion of the iconic Moore/Bolland graphic novel. Doesn’t add much except running time; for completists only, perhaps, though those unfamiliar with the book may appreciate it more.

Batman (1989, dir. Tim Burton)

Batman creates – and battles – the Joker. Mixing expressionism, noir, Hammer horror and pop art, the 1989 Batman is well-tailored from patches and the need to service a guest villain performance, even if it doesn’t really have a story. Still fun, tho, with a lovely mix of technologies working together. Best of all, it feels like a comic book. Sequels followed.

Joker (2019, dir. Todd Phillips)

A clown with mental health issues tries to be loved and recognised. Well-shot but superficial origin story, heavily reliant on its stylistic and plot inspirations (early Scorsese movies, Bernhard Goetz). Sometimes impressive, sometimes misguided, but anchored by a committed central performance nevertheless.
