Here's the official poster for "Joker" the new movie starring Joaquin Phoenix (as the Joker)
From Deadline:
The standalone film directed by Todd Phillips and starring Joaquin Phoenix is set to open Oct. 4. The poster (as seen below) features Phoenix in the title role leaning back and looking to the heavens in full, smeared Joker makeup and what seems to be blood with the tagline “Put on a happy face.”
Our only other looks has been this "screen test" that popped up last September
