Joker: Folie à Deux Trailer Unveiled, Introduces Lady Gaga’s Harley Quinn

The first trailer for “Joker: Folie à Deux” premiered following Warner Bros.’ presentation at CinemaCon in Las Vegas, offering fans an eagerly awaited glimpse into the sequel of Joaquin Phoenix’s portrayal as Arthur Fleck/Joker. This new installment not only heralds the return of Phoenix but also introduces Lady Gaga’s take on Harley Quinn, marking a significant evolution in her character’s backstory. The trailer places a substantial emphasis on Arthur, yet Warner Bros.’ tagline, “he’s not alone anymore,” and the showcased scenes suggest that Harley’s narrative will be equally central. Notably, the trailer departs from the traditional depiction of Harley Quinn as a psychiatrist, instead presenting her as a patient in Arkham Asylum, indicating a pivotal change in her origin story.
