In 2019, the whole world met Arthur Fleck, a down-on-his-luck clown who would come to be known to everyone as Joker. The DC Elseworlds film took audiences by storm, dancing its way to $1B at the box office and a Best Picture nomination (not to mention a Best Actor win for Joaquin Phoenix). But now Arthur is back in Joker: Folie à Deux, and this time, he’s not alone anymore.

What is Folie à Deux? Well as multiple fans have wondered and discovered, it means a shared delusional disorder. And Arthur Fleck can’t experience this without someone to share it with. Thus, Joker: Folie à Deux will at last introduce the world to Lady Gaga’s version of Harley Quinn!

In the new trailer, we get a lot more of a glimpse at Gaga’s Harley, and a bit more on what the story is going to be about. But don’t let me keep you from checking it out for yourself.

Everything about this trailer looks nuts! But you know what? If they wanna get nuts, c’mon! Let’s get nuts!

Joker: Folie à Deux officially hits theaters October 4!
