Lady Gaga and Joaquin Phoenix used to think life was a tragedy, but now they realize it's a comedy.

The duo fully embraced their clownish delights in the first trailer for Joker: Folie à Deux, a sequel to the 2019 film Joker. In the new trailer, released at CinemaCon April 9, Joaquin reprises his role as the title character (real name Arthur Fleck), while Gaga takes on the iconic role of Harley Quinn, who in the DC comics serves as the Joker's lover and partner in crime, despite it being a toxic relationship for both of them.
