Joker: Folie à Deux, the sequel to Todd Phillips’ Joaquin Phoenix-starring King of Comedy riff was inevitable since it took the box office by storm and nabbed Phoenix an Oscar. But how do you top that first go around? The only logical answer is to bring Lady Gaga on board.

It was announced last year that Gaga would take on the next iteration of Harley Quinn in Joker: Folie à Deux, which, somehow is… a musical? Yes, the sequel to Joker is a musical, this isn’t a joke, if you pardon the pun. How the semi-realistic landscape of Joker’s Gotham universe will introduce a bit of song and dance is anyone’s guess, and we still have a bit longer to wait to find out.

In the meantime, here’s everything we do know about Joker: Folie à Deux.

What is Joker: Folie à Deux about?

The big question – What on earth is this film going to be about?

While no one is entering a superhero adaptation thinking the door is closed on sequels, 2019’s Joker set up a bleak future for Gotham that’s fallen into anarchic disrepair. With it still up in the air whether Todd Phillip’s world of The Joker is set to overlap with Matt Reeves’ The Batman (although, unlikely, seeing as Barry Keoghan nabbed that cameo as the psychotic clown), this next iteration seems to be about The Joker’s other great partner: Harley Quinn.

The drip feed of Joker 2 content has been sparse and intermittent since its first announcement, maybe a bit of guerilla marketing to make us all go insane with anticipation. Still, we’ve got another clue to add to our tiny stack of playing cards, as a picture of Joaquin Phoenix’s Arthur Fleck out of his full clown glam has been released. It doesn’t give much away about the still-mysterious plot, however, given that Fleck was last seen locked up in Arkham Asylum, it does allude to him at least being freed at some point. Although maybe that’s all in his head – he does have a habit of doing that.

In the still, he’s surrounded by umbrellas looking up at the sky, eyes closed as rain pours down on him. Is it too much to hope this is the lead-up to a stunning rendition of co-star Lady Gaga’s song “Rain on Me”? This is a musical after all.
