Lady Gaga posted on social media today a teaser video titled “Joker: Folie à Deux 10.04.24”, which revealed her role as a major character in the film as we can see silhouettes of her and Phoenix dancing to the song “Cheek to Cheek”, which she covered with Tony Bennett. Fans believe that her character is going to be Harley Quinn, the iconic romantic interest to the Joker and that the sequel may not simply be continuation of the first film, but a musical instead. The film is set to release on October 4th, 2024.
