Joker: Folie à Deux. The 60-second video features Lady Gaga's Harley Quinn visiting an emaciated Arthur Fleck, or Joker, played by Joaquin Phoenix, who is in a mental institution. Before she leaves, she pulls out a red lipstick and smears a clownish grin,

What we know about Joker: Folie à Deux is limited, but that'll change when it hits theaters in October. And while Joaquin Phoenix encouraged Gaga to sing poorly, that's simply not the case in the final Joker 2 trailer. Mother Monster shared th enw clip on her Instagram, check it out below:

Folie à Deux' co-star Joaquin Phoenix said she lost "a lot" of weight for it. Here's what to know about her diet and fitness routines.

Joaquin Phoenix had one note for Lady Gaga while shooting "Joker: Folie à Deux": sing worse. This isn't "A Star Is Born."

Folie à Deux does have quite a few scenes featuring music, Lady Gaga, who plays Harley Quinn, doesn't think of it as a musical at all.

EW's exclusive clip from the "Joker" sequel shows Gaga and Phoenix passionately kissing before passing a puff of cigarette between their lips.

Joker and Harley Quinn are sharing their madness with Gotham City as mayhem reigns in the trial of Arthur Fleck.

Since it was revealed that singing will be part of the sequel, there's been discourse about whether or not the Joker 2 was a musical. Both Todd Phillips and Lady Gaga claim it is not, although the way that music is used sounds like a textbook musical. So it should be fascinating to see how it all shakes out once the movie hits theaters in October.

Director Todd Phillips and his stars were showered with a 10.5-minute standing ovation inside Venice's Sala Grande cinema Wednesday night as they unveiled their follow-up to 'Joker', which won the prestigious Golden Lion in 2019.

That certainly looks to be the idea in the latest trailer for Todd Phillips all-singing, all-dancing movie with music Joker: Folie À Deux, which sees Joaquin Phoenix's Arthur Fleck taking to the stand as he goes on trial for the televised killing of Murray Franklin (Robert De Niro) in Joker.
