No joke: Lady Gaga really will star opposite Joaquin Phoenix in a sequel to 2019′s “Joker,” the pop superstar confirmed Thursday.
According to Variety and CNN, the 36-year-old actress and singer took to social media to share the news, posting a teaser for the upcoming film, titled, “Joker: Folie à Deux.” In the 18-second animation, the song “Cheek to Cheek” plays as the silhouettes of a man and woman appear to dance and embrace, Variety reported. The clip concludes with the movie’s release date – Oct. 4, 2024 – and the sound of haunting laughter.
The tweet came less than two months after several news outlets, including The Hollywood Reporter and Entertainment Weekly, reported that Gaga was in discussions to appear as Harley Quinn in a “Joker” musical sequel. But the performer – who won an Oscar for best original song, “Shallow,” in the 2018 film “A Star Is Born” – wouldn’t be considered a replacement for Margot Robbie, who has portrayed Quinn in other DC films, according to the reports that surfaced in mid-June. The “Joker” sequel’s Quinn “exists in a different universe” from Robbie’s version of the character, The Hollywood Reporter wrote at the time.

Earlier in June, “Joker” director Todd Phillips shared an Instagram photo of the cover of the sequel’s script. A second image showed Phoenix, 47, looking over the script, which was written by Phillips and Scott Silver, according to the post.
