Run for your life! Bill Skarsgard popped up on Conan O’Brien Tuesday night and debuted his creepy clown smiles without the makeup. And yes, it’s just as scary. As he explained, “My older brother Gustaf, who’s an actor as well, he had this ability to do, you know, point his lip in a very strange way and for some reason, I don’t know how, I understood that I could do it as well.” He’s been doing it since he was a kid, and when he was 10, he even created a character around the freaky smile. His brother is still traumatized. Have you seen It yet?
