It was captioned: “Work.” It is unclear if the clown is Phoenix.

Earlier this month, Phillips gave fans a first glimpse at Phoenix’s Joker. He shared a picture to Instagram showing the actor with long hair and captioned it: “Arthur.”

The Joker’s real name in the film is Arthur Fleck. Phillips later posted a video showing Phoenix in clown make-up.

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 released in October 2019.
