Catherine Keener to do the Batdance with Joaquin Phoenix and Lady Gaga in Joker musical sequel

The Oscar-nominee will play an undisclosed role in Joker: Folie à Deux, the musical sequel to Todd Phillips' 2019 hit film.

The musical nobody asked for is quickly becoming the must-see film of 2024.

Catherine Keener, noted MVP of many a film and occasional TV project, has joined the cast of Joker: Folie à Deux, EW has confirmed.

The sequel to Todd Phillip's 2019 controversial blockbuster, which brought star Joaquin Phoenix a long overdue Oscar, will be a musical reuniting Phoenix, Phillips, and his co-screenwriter Scott Silver.

Also along for the ride is Lady Gaga as the Harley Quinn to Phoenix's titular Clown Prince of Crime. Folie à Deux will reportedly be set in Arkham Asylum, the notorious super-jail housing Gotham's criminal elite in the Batman universe. It's unclear who Keener will be playing, though sources claim it is a "major role."

Hmmm, a major female role in a Batman-related movie set in a prison for villains ... sounds like we've got at least two options to consider: Catwoman or Poison Ivy. Catherine Keener would be great as either. But in all fairness, Catherine Keener would be great just reading a telephone book.

Zazie Beets, crossing over from one adjacent-superhero cinematic universe to another, and Brendan Gleeson, who's currently stirring up Oscar buzz himself for The Banshees of Inisherin have also joined the cast of the Joker sequel.
