"Joker" director Todd Phillips has shared yet another tidbit from his upcoming Batman villain drama starring Joaquin Phoenix. This time, he posted the first poster to Instagram — and also revealed that the first teaser trailer will drop tomorrow.

The poster doesn't reveal much — not even all of Phoenix's face in the Joker's iconic clown makeup — but it certainly hints that this won't be your standard comic book movie.

Not much is known about the movie other than that it is an origin story of how Arthur Fleck became the infamous villain. Phillips has previously shared a brief look at Phoenix laughing in make-up and a behind-the-scenes glimpse at Zazie Beetz, who plays a single mom who catches the Joker's eyes.

“The approach that Todd Phillips has taken is more of an origin story and a character study of a mentally ill person that becomes The Joker,” co-star Marc Maron told NME. “It’s more of an intimate and gritty movie with a very specific scope. It’s going to be really interesting to see how it comes out.”

"Joker" opens in theaters October 4.
