Joaquin Phoenix has been pictured as the Joker for the first time.
The US actor, 43, is set to play the Batman baddie in an as-yet-untitled film.
Film-maker Todd Phillips, who is directing the movie, shared the first look image on Instagram on Sunday night.
It shows Phoenix with longish hair and a drab jacket and is captioned simply: “Arthur.”
The film will look at the character’s origins. Previous reports suggested he will be a stand-up comic who turns to crime after his career fails to take off.
The Joker film is due to be unveiled in 2019.
