Folie à Deux,” Lady Gaga will introduce audiences to Lee Quinzel, her version of the Joker’s love interest Harley Quinn from the DC comic books.

Folie à Deux, particularly for its introduction of pop superstar Lady Gaga into the role of Harley Quinn. Although this version of Harley will be decidedly different from her comic book counterpart, fans are still eager to see what Gaga will bring to the role.

In an interview with CNN, Gaga explained just how much she had to change her typical approach to performing for the movie, which does double duty as a somewhat pared-down musical and a dark love story between Joker, a.k.a. Arthur Fleck (Joaquin Phoenix), and Gaga’s character.
