Joker: Folie à Deux

Joker: Folie à Deux is a 2024 American jukebox musical legal drama film directed by Todd Phillips from a screenplay he co-wrote with Scott Silver. Based on DC Comics characters, it is the sequel to Joker (2019). Joaquin Phoenix stars as Arthur Fleck / Joker, reprising his role from the first film, alongside Lady Gaga as Harleen "Lee" Quinzel. The main cast includes Brendan Gleeson, Catherine Keener and Zazie Beetz, with supporting appearances from Steve Coogan, Harry Lawtey, Leigh Gill and Connor Storrie. In the film, while awaiting trial for his crimes at Arkham State Hospital, Arthur develops a romantic relationship with fellow inmate Lee. As the trial begins, he questions his path when he realizes Lee and others only see him as Joker.

Although Joker was intended to be a standalone film, its success at the boxoffice sparked interest in a sequel. Warner Bros. eventually convinced Phillips and Phoenix to return, with more creative freedom and a significantly greater budget. The film was announced in June 2022, with Gaga and Beetz joining later that year. Principal photography took place in New York City, Los Angeles, and Belleville, New Jersey, from December 2022 to April 2023.

Joker: Folie à Deux premiered at the 81st Venice International Film Festival on September 4, 2024, and was released in the United States on October 4. The film was poorly received by critics and became a box-office bomb, grossing $208 million on a $190–200 million budget. Among its seven Golden Raspberry Award nominations it won Worst Remake, Rip-off or Sequel and Worst Screen Combo for Phoenix and Gaga.
