Director Todd Phillips shares behind-the-scenes picture from Joker film set

Director Todd Phillips has shared a behind-the-scenes picture from the upcoming Joker film.

The movie will star American actor Joaquin Phoenix as Batman’s arch nemesis and is due to be released next year.

The picture, posted to Phillips’s Instagram page, shows an actor dressed as a clown sitting down during a break in filming.

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.
