‘Joker: Folie a Deux’ Trailer: All the Easter Eggs You Missed

Joker: Folie à Deux just debuted its first trailer, featuring the return of Joaquin Phoenix’s Joker and the debut of Lady Gaga’s Harley Quinn. This franchise is set in its own separate DC universe, with no other superheroes or villains — at least that we know of so far. But that doesn’t mean the film isn’t indebted to the long history of DC Comics, or that it doesn’t contain references to other movies — especially Hollywood musicals from the Golden Age.

For a look at all those references, check out our latest ScreenCrush video, which picks apart the Joker: Folie à Deux trailer, explains what the first movie tells us about this sequel, what to expect about what is real in Joker 2 and what may be happening inside the mind of Phoenix’s Arthur Fleck, and why the musical is the perfect genre to explore the twisted psyches of Joker and Harley. Watch our full breakdown of the trailer below:
