The Joker and Harley Quinn are caught in a bad romance in the latest trailer for Joker: Folie à Deux, the highly anticipated sequel to Todd Phillips’ Joker. Venturing into the twisted psychosis of the Joker and Harley Quinn, the new trailer witnesses their blooming relationship and dangerous impact on others.

It starts with Arthur Fleck (Joaquin Phoenix) unable to suppress laughter in the back of a police car while radio commentators discuss his status, with some considering him a martyr while others call him a monster. At Arkham Asylum, he meets Harleen Quinzel (Lady Gaga) and is quickly taken with the equally unhinged patient.

As their love grows, so does their madness, and the pair inspire anarchy in the streets of Gotham. This is taken a step further with musical numbers, and Arthur – in full Joker makeup – violently defending himself in court.

Phillips returned to helm the sequel and Zazie Beetz is back as Sophie Dumond. Joker: Folie à Deux also stars Catherine Keener, Brendan Gleeson, Ken Leung, Steve Coogan, John Lacy, and Bill Smitrovich. It will arrive in theaters on October 4, 2024.
