Todd Phillips’ eagerly awaited sequel to Joker leans towards being “mostly a jukebox musical,” integrating at least 15 reinterpretations of “very well-known” songs.

One is said to be “That’s Entertainment” from Minnelli’s 1953 musical The Band Wagon, starring Fred Astaire and Cyd Charisse.

However, one or two original songs will be added to the final version. But no Details yet regarding who would pen the tracks, or sing the numbers.

Hildur Guðnadóttir, the Oscar-winning composer of the first Joker film, is expected to infuse her distinctive, haunting music cues” into each number.

Joker 2 is expected to break the mold of traditional musicals.

Phillips collaborated on the screenplay with Scott Silver.  Specific details about the plot of “Folie à Deux” have not been confirmed, but the film is described as a drama with elements taking place in and around Arkham Asylum.

Alongside Phoenix and Gaga, the cast includes Emmy nominee Zazie Beetz (“Atlanta”), Oscar nominees Catherine Keener (“Being John Malkovich”) and Brendan Gleeson (“The Banshees of Inisherin”).

The first Joker movie, a Golden Lion winner at the Venice Film Fest, grossed over $1 billion worldwide and led the Oscars with 11 nominations.

Early discussions are under way for possible premiere at this year’s Venice Film Festival.

Phoenix clinched the best actor Oscar award for his portrayal of Arthur Fleck, a mentally ill party clown who makes his transformation into the famed DC villain.

Gaga, a 13-time Grammy winner, has made a successful transition to Hollywood, evident in her Oscar win for co-writing the original song “Shallow” (alongside Mark Ronson, Andrew Wyatt and Anthony Rossomando) for Bradley Cooper’s “A Star is Born” remake in 2018.

Gaga was also nominated for best actress that year, making her one of only 4 individuals in history to receive acting and songwriting nominations simultaneously.
