The highly anticipated film 'Joker: Folie à Deux' is scheduled for release in theaters on October 4.

In this sequel, Arthur Fleck, played by Joaquin Phoenix, faces the death penalty and is involved in a twisted romance with Lady Gaga's character, Harleen 'Lee' Quinzel, who becomes Harley Quinn.

Set two years after the original film, the storyline follows Arthur as a patient at Arkham State Hospital.

Director Todd Phillips has integrated musical elements into the film, emphasizing that much of the music serves as dialogue expressed through song rather than traditional musical numbers.

In a unique approach, only Phoenix and Gaga's characters sing and dance, with many musical numbers existing in their minds, reflecting their shared madness.

Gaga described her role as a significant creative leap, adding 'audacity and complexity' to the story with her musical contributions.

Phillips aims to present a grittier and more realistic version of Harley Quinn, stripping away her traditional comic traits such as her high voice and sass.

This portrayal aligns with the darker Gotham world established in the first film, where Harley's character is depicted as a patient rather than a doctor.

Both Phoenix and Gaga focused on delivering honest performances in their musical numbers, prioritizing raw emotion over technical perfection.

The cast also includes Emmy nominee Zazie Beetz and Oscar nominees Catherine Keener and Brendan Gleeson, showcasing a strong ensemble.

Phillips has stated that he feels the story of the Joker has been fully explored across these two films, with no plans for a third installment.

Fans are encouraged to stay tuned for updates on future DC projects, including 'The Batman 2' and a spin-off titled 'The Penguin.'
