Joker: A well-known DC comic book sequence that was hinted at in 2008’s The Dark Knight can now be adapted by Folie à deux. Hard-hitting drama based in a comic book universe is The Joker (the first one). Although it stays away from the comedic elements of Gotham City, it does feature certain well-known Batman figures, such as a young Bruce Wayne and Thomas Wayne. Joker 2 might bring more details to DC mythology, especially now that Harley Quinn is involved. In addition, a number of well-known antagonists might make an appearance while Arthur is imprisoned in Arkham.

As Joker: Folie à Deux nears its release, new images and details are being shared, giving a better look at who else is in the cast. A trailer shared on Instagram by Warner Bros. included a brief glimpse at Harvey Dent, played by Harry Lawtey. Most people know Dent as the District Attorney who transforms into Two-Face, but Joker 2’s version is before his face is scarred beyond repair. However, this gives Joker 2 the perfect opportunity to give audiences Dent’s comic book origins, a moment that was teased but altered by Christopher Nolan in The Dark Knight.
