Summary
- Gaga's performance as Harley Quinn in Joker: Folie à Deux should involve her descent into madness.
- Joker: Folie à Deux may focus more on Gaga's Harley Quinn than on Joaquin Phoenix's Joker, with Harley's impact on the story already felt in the sequel's name.
- The fact that Joker: Folie à Deux will be a musical suggests that the film may prioritize Gaga's Harley Quinn and her story over Phoenix's Joker, aligning with the franchise's tendency to break expectations.
