Joker 2 - Lady Gaga is in talks to play Harley Quinn opposite Joaquin Phoenix in the upcoming sequel

The sequel is said to be a musical, which would make Lady Gaga perfect for the role. The movie's working title is Folie à Deux, this is also the name of a mental illness.

In which two people share the same delusion, this usually happens between family members.

Like 2019s Joker , this movie will be set outside of the DCEU , so this version of Harley Quinn will be different from Margot Robbie 's portrayal.

Another important thing to remember despite director Todd Phillps posting a picture of Joaquin Phoenix reading the script, he hasn't officially signed on to the project.

Todd Phillps reunited with Scott Silver to write the script, the movie being a musical seems to be an interesting choice.

Considering the duo's previous success with Joker, this direction for the sequel could pay off.

Joker was one of the top-grossing movies of 2019 and grossed over one billion dollars worldwide becoming the first R-rated to do so and making it the highest of all time.

The movie was nominated for eleven Oscars at the 92nd Academy Awards and won for Best Actor and Best Original Score.

Actor Willem Dafoe has also expressed interest in being a part of the project multiple times and is a fan favorite. The rest of the cast and more details about the movie should be revealed in the coming months.

For now, we will have to wait and see how Arthur Fleck's story continues.
