Although Joker was initially conceived as a standalone film, its success at the box-office 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 officially 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 failure, grossing $207.5 million worldwide 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.
