In 2019, Joaquin Phoenix and director Todd Phillips gave the Joker a new origin story, as Phoenix’s Arthur Fleck embraced his new persona. Later this year, Phoenix and Phillips are returning for the sequel, Joker: Folie à Deux. They will be joined by Lady Gaga, who will step into the role of Harleen Quinzel/Harley Quinn and fall madly in love with Joker. Now, Lady Gaga is offering some insight about her take on Harley.

“Lee is very special to me,” Gaga told Access. “She’s a truly vulnerable, sweet person. My version of Harley is mine and it’s very authentic to this movie and these characters. I don’t want to give anything from the movie away. It’s really something you have to experience in the theater. This film has music, it has dance, it has amazing acting in it. I loved working with Joaquin, I loved working with Todd.”

“I’ve never done anything like I’ve done in this movie before,” added Gaga. “So it’s all going to be completely brand new and really fun.”

Only a handful of cast members from the first Joker are returning for the sequel, including Zazie Beetz, Leigh Gill, and Sharon Washington. The new cast members for the film include Brendan Gleeson, Catherine Keener, Jacob Lofland, Steve Coogan, Ken Leung, and Harry Lawtey.

Joker: Folie à Deux will hit theaters on October 4.
