The movie will be an “exploration of a man disregarded by society [that] is not only a gritty character study, but also a broader cautionary tale,” Warner Bros. told The Hollywood Reporter in July.
The movie will have no impact on the DC Universe, in which Jared Leto stars as Joker, according to Variety. Warner Bros is developing a separate stand-alone Joker film for Leto, which will be within the confines of the DC Universe.
Prior to Phillips releasing the photo of Phoenix in-character, but without his trademark makeup and suit, TMZ unearthed a set video showing the star in action.
Phoenix’s Joker origin film is set to be released Oct. 4, 2019.
