A new Joker 2 set video features Lady Gaga's Harley Quinn singing. The film, officially titled Joker: Folie à Deux, is set to be a musical.
In the video, we don't actually see Harley in action, but you can hear her giving a rendition of a classic tune. The song sounds a lot like "Couple of Swells," sung by Judy Garland and Fred Astaire in the film Easter Parade. Significantly, that's a song for a double act, but whether Joaquin Phoenix's Joker is duetting in this particular number is a mystery for now.
