The trades mentioned that Todd Phillips' Joker sequel, Folie à Deux, would feature musical numbers back when the movie was officially announced, and recent set videos spotlighted Lady Gaga's Harley Quinn dancing down the first film's familiar steps while singing a few lines from Arthur Schwartz and Howard Dietz's "That's Entertainment."
Even so, we still haven't received official confirmation that Joker 2 is going to be a full on musical.
While speaking to ComicBook.com during the A Haunting in Venice press junket, Joker: Folie à Deux composer Hildur Guðnadóttir - who nabbed an Oscar for the first movie's stunning score at the 92nd Academy Awards - was asked about those early reports, and while she declined to confirm anything outright, her response was very telling.
"All I can say is there is going to be a lot of music," Guðnadóttir offered. "That's all I can give away."
While some fans are a little resistant to the idea of a follow-up to Phillips' dark psychological thriller being a musical, others have embraced the concept. We're still not sure exactly how these songs will be implemented into the story, but rumor has it that the narrative will be split between Harley and Arthur Fleck's (Joaquin Phoenix) skewed perspectives, so there's a chance the musical numbers will simply be part of the characters' delusions (Fleck imagined his entire relationship with Sofie Dummond in the first film, after all).
Whatever form the songs take, we have heard that the soundtrack will be "heavily inspired" by classic Liza Minelli musicals such as Cabaret, New York, New York, and That's Entertainment. This isn't really too surprising, since Lady Gaga is a big Minelli fan.
We still don't know if the pop megastar is actually writing the soundtrack, but we'd say there's a decent chance she'll pen at least one song for the movie.
In addition to Phoenix and Gaga, Joker 2 will see the return of Zazie Beetz as Sophie Dumond, along with new cast members Brendan Gleeson, Catherine Keener, Jacob Lofland and Harry Lawtey in undisclosed roles.
The Joker sequel won't take place in the same world as the main DCU, and will be known as an "Elseworlds" project, along with Matt Reeves' The Batman movies, J.J. Abrams' Superman film, and Constantine 2 (if they happen).
Joker: Folie à deux is set to hit theaters on October 4, 2024.
