Lady Gaga Shares Poster for ‘Joker: Folie à Deux’

Fans of Joker can rejoice—an official sequel to Todd Phillips’s acclaimed 2019 film is happening, this time with Lady Gaga along for the ride.

Gaga confirmed the major casting news online in August 2022, simply posting, “Joker: Folie à Deux 10.04.24,” alongside a quick clip featuring the silhouettes of Joaquin Phoenix’s Arthur Fleck—a.k.a. the Joker—and what fans even then assumed was the shadow of Harley Quinn, the Batman villain’s most famous love interest.

In cartoons and comics, Harley Quinn is the criminal persona of Dr. Harleen Quinzel, a psychiatrist at Gotham City’s Arkham Asylum who eventually falls in love with her psychotic green-haired patient. Joker: Folie à Deux reportedly takes place in a universe separate from Suicide Squad and other DC Comics movies starring Barbie’s Margot Robbie as Harley.

Joker made more than $1 billion worldwide at the box office and scored Phoenix his first Oscar, for Best Actor. Though the plot for the sequel is still tightly under wraps, Phillips is returning as director and this film is supposed to be a musical.

While the Joker has always been one of the DC Universe’s more disturbed characters, in Phillips’s version of his origin story, he was especially so. Following the film’s release, critics debated the wisdom of making a film like Joker, especially as the United States continues to be plagued by mass shootings and violence.

Adding Gaga to the mix seems like a calculated move to influence more women to hit the theater for the sequel. And it might work: Aside from being an international pop star, Gaga is a damn good actress. Not only was she nominated for a Best Actress Oscar for her role as Ally in 2018’s A Star Is Born, she also won the Academy Award for Best Original Song that year, for “Shallow,” from the same film. In 2022, she was famously snubbed for her portrayal of Patrizia Reggiani in Ridley Scott’s House of Gucci.

Ahead, we answer your big questions about Joker: Folie à Deux.

When does Folie à Deux come out?

The sequel will hit theaters October 4, 2024. In early April 2024, Lady Gaga posted an official poster for the film on her Instagram, writing, “The world is a stage. Joker: Folie à Deux trailer coming April 9.” The main image features her Quinn and Phoenix’s Joker dancing together.

The first trailer shows the origins of Joker and Harley Quinn’s relationship.

The first teaser trailer for the film, released April 9, finally introduces the world to Gaga’s Harley Quinn. Fans were instantly convinced by the pop star’s portrayal of the iconic antihero. In the clip, viewers see the Joker and Quinn’s relationship beginning to blossom—in an insane asylum, of course.

What is the movie about?

The filmmakers have kept mum about the sequel’s full plot, but we do know this film will be a jukebox musical—another likely reason for Gaga’s casting. She shared a first look at her character alongside Phoenix’s Joker as a Valentine’s Day treat for fans in 2023.

Gaga was also spotted filming a big sequence for the movie in New York City in 2023. She was photographed wearing a stylish iteration of Quinn’s iconic black, white, and red costume, surrounded by cops and cheering at the crowd during what looks like a protest.

The multi-hyphenate has also shared an up-close look at her Quinn in April 2023, by way of a selfie marking the end of filming. Gaga shared a pic of her character in a somber black look, wearing faded clown makeup and smudged lipstick.

“That’s a wrap ❤️‍🔥 🎬🃏 X, Harleen,” she wrote.
