Joaquin is the latest star to take on the iconic DC Comics character, which has previously been played by Jack Nicholson, Heath Ledger and Jared Leto, in a new film exploring his back story.
In the new chilling two-minute trailer, we’re introduced to Arthur Fleck, an aspiring stand-up comedian who, after a series of tough knocks, invents the persona of The Joker.
The teaser also explores Arthur’s (unusual) relationship with his mother – played by Six Feet Under and American Horror Story actress Frances Conroy – and repeatedly alludes to mental illness, with Joaquin’s character visiting a psychiatric facility, and writing about his issues in his diary.
The trailer is set to the jazz standard Smile, and at the end, Joaquin is heard saying: “I used to think my life was a tragedy, but now I realise, it’s a comedy.”
While the film’s titular character has recently been seen in Christopher Nolan’s Dark Knight trilogy and the DC adaptation Suicide Squad, Joker will serve as a stand-alone film, with child actor Dante Pereira-Olson set to play a young Bruce Wayne, years before he invents his Batman persona.
Also among the cast are Robert DeNiro, who plays a talk show host who interviews the Joker, and Atlanta star Zazie Beets as Arthur’s love interest Sophie Dumond.
Joker is set for release in cinemas worldwide in October 2019.
