Todd Phillips' Joker has long been rumored to be R-rated, and the director has now confirmed that fact with a new still from the film.

Shared by Phillips on Instagram, the image shows Joaquin Phoenix, who stars as the Clown Prince of Crime, looking into a mirror and applying makeup. In response to a question on the post about the film's rating, Phillips replied, "It will be Rated R. I’ve been asked this a lot. Just assumed people knew. Sorry."

That rating shouldn't come as a surprise to those who've been following the progress of the film, which is said to be a dark, gritty take on the Clown Prince of Crime. The movie's first trailer confirmed it's set in the 1980s and will feature the Wayne Family. Co-star Marc Maron has described Joker as "an origin story and a character study of a mentally ill person that becomes The Joker."
