Lady Gaga discussed this subject while explaining how the movie inspired her new album Harlequin, which collects reimagined covers that she and Phoenix sing in Joker, as well as two original songs. The singer-songwriter and star of movies like A Star is Born and House of Gucci started off by telling EW:

As Joker 2 nears its release, director Todd Phillips has opened up about the future of Lady Gaga’s Harley Quinn. During a red carpet event, Phillips discussed the possibility of a standalone film for Gaga’s Harleen Quinzel.

I think it’s a beautiful thing when you can, with your partner, share an artistic experience that might be hard for some people," Gaga tells EW of Michael Polansky.
