The upcoming Joker sequel, Joker: Folie à Deux, is gaining another star, as Deadline is reporting that Catherine Keener is set to join the film.
The film will feature the return of Joaquin Phoenix as he reprises his Oscar-winning role as the titular DC villain.
Keener’s role is unannounced as of now, but the actress will join a star-studded cast that’s set to include Joaquin Phoenix, Lady Gaga, Zazie Beetz, and Brendan Gleeson.
Filming is expected to get underway later this year in December, so we’ll likely know more about who Keener will be playing by then.
