Lady Gaga's upcoming album, titled 'Harlequin', will serve as a companion piece to the film 'Joker: Folie À Deux', which is set to hit theaters on October 4.

Joaquin Phoenix, who reprises his role as Arthur Fleck, initially hesitated about a sequel but found new creative avenues to explore after discussions with director Todd Phillips.

Phillips describes the film as incorporating musical elements, yet it diverges from traditional musicals by infusing a sense of sadness, which he believes sets it apart.

The film features fantasy sequences and musical numbers that enhance the narrative, showcasing the complex relationship between Arthur and Harley Quinn.

In a poignant scene, Gaga's character applies makeup to Arthur, symbolizing her desire to see his true self.

The chemistry between Phoenix and Gaga is emphasized as a crucial aspect of the film, highlighting their vulnerability amid larger-than-life personas.

Gaga expressed her excitement about collaborating with Phoenix and Phillips, noting that the experience was unlike anything she had done before.

She described her portrayal of Harley Quinn as authentic and unique, encouraging audiences to experience the film in theaters.

Several songs on the album reference iconic artists, including Frank Sinatra and Louis Armstrong, showcasing Gaga's musical influences.

Gaga has been teasing the album's announcement on social media with cryptic posts, building anticipation among fans.

The film premiered at the Venice Film Festival earlier this month, receiving mixed reviews but noted as an improvement over the original.

While musical numbers are present, they are perceived as somewhat artificial, primarily enhancing Gaga's performance rather than Phoenix's.
