Lady Gaga Reveals Latest Joker: Folie à Deux Trailer With A Familiar Face

In Joker, the title character--Arthur Fleck (Joaquin Phoenix)--was so lonely that he had to imagine a romantic relationship with Sophie Dumond (Zazie Beetz), a neighbor whom he barely knew. But in Joker: Folie à Deux, Gotham City's Clown Prince finally has his Harley Quinn, as played by Lady Gaga. And in the newest trailer for the sequel, these crazy lovebirds are going to spread a little madness around town.

Gaga posted the trailer on her X account, which includes a few new moments from the film. Given Joker's insanity, it's hard to tell if some of the courtroom scenes are real or simply something Arthur daydreamed. But there is one familiar face from the original film, Gary Puddles (Leigh Gill), who is absolutely terrified when he comes face-to-face with Joker in court. Before Arthur became Joker, Gary was one of his only co-workers who was actually nice to him. That's the only reason Joker let him live the last time they met.

We can probably safely assume that Joker and Harley's Sonny and Cher-like variety show is a delusion, but at some point they will be together outside of Arthur's murder trial. In one scene, Arthur sees Gotham's District Attorney, Harvey Dent (Harry Lawtey), denouncing him on television. If we had to make a bet, it seems likely that Joker will ultimately have the last laugh when it comes to Harvey. But we don't know if Harvey will have his own transformative experience on his way to becoming Two-Face.

Joker: Folie à Deux will be released in theaters October 4. But don't expect a third film to make it a trilogy. Director and co-writer Todd Phillips has already ruled out Joker 3.
