Lady Gaga signs on to play Harley Quinn in Joker MUSICAL sequel alongside Joaquin Phoenix for Warner Bros. and director Todd Phillips

Just days after writer-director Todd Phillips shared the title of his Joker sequel – Joker: Folie a Deux – Lady Gaga has joined the cast as the iconic Harley Quinn.

Gaga, 36, is reportedly in early talks to play the DC Comics character, according to a new report from The Hollywood Reporter, which also reveals the project is being developed as a musical.

Margot Robbie has played Harley Quinn in 2016’s Suicide Squad, 2020’s Birds of Prey and 2021’s The Suicide Squad, though this version of Harley Quinn in Joker: Folie a Deux is said to exist in a different DC universe than Robbie’s Harley Quinn.

While the original 2019 Joker was never intended to have a sequel, its critical and commercial success lead director Todd Phillips said in August 2019 that he might be interested in making a sequel, if Phoenix were interested in returning.

Phillips signed on to direct and co-write the script with his original Joker writing partner Scott Silver in May 2021.

Last week, Phillips shared a photo of the Joker: Folie a Deux script cover, revealing that script draft was completed on May 18.

He also shared another photo of Phoenix reading the script while smoking a cigarette, though THR clarified Warner Bros. has not yet finalized a deal with Phoenix, though they are both ‘deep’ in negotiations.

The title Folie a Deux is a medical term that is, ‘an identical or similar mental disorder affecting two or more individuals, usually the members of a close family.’

The 2019 R-rated Joker movie was a surprise smash hit at the box office, which earned $335.4 million domestic and $1.074 billion worldwide from a meager $55 million budget.

The Harley Quinn character was by Paul Dini and Bruce Timm in 1992 for Batman: The Animated Series.

While she was only intended to appear in one episode as comedic relief, she became a recurring character and ultimately the Joker’s sidekick and love interest.

She was introduced into the DC Comics universe in 1999 as the Joker’s love and partner in crime, and also a good friend of supervillain Poison Ivy.

The singer/actress (born Stefani Joanne Angelina Germanotta) followed up her Oscar-nominated performance by playing Patrizia Reggiani in last year’s House of Gucci.

She also recently wrote the song Hold My Hand for the current box office hit Top Gun: Maverick.
