The Joaquin Phoenix-led 2019 film Joker was a massive critical and commercial success. The film grossed over $1 billion at the global box office and also won numerous accolades, including an Oscar Award for Best Actor.
Naturally, a sequel, Joker: Folie à Deux, is in the works. The movie is currently filming and, according to recently released set photos, it might feature another iconic Batman villain, Two-Face, whose real name is Harvey Dent.
Throughout several adaptations, Dent is the District Attorney and former Bruce Wayne pal who eventually became one of his greatest adversaries, Two-Face.
The set photos showed protesters gathering in front of a courthouse with signs proclaiming "Free Joker," "Joker 4 President," "No Justice in Gotham," and "Dent is A Clown." While Harvey Dent didn't feature in the first film, Folie à Deux will tell a new story and the character could very well feature. However, there is no way to know for sure as there is little to no information available about the film.
