The Terrifier - David Howard Thornton
David Howard Thornton goes over-the-top for The Terrifier. He plays villain Art the Clown and is portrayed as a horrifying clown with a white painted face, black overlined lips, long nose, and bloody teeth.
The Babadook - Tim Purcell
Although viewers don't see The Babadook himself much throughout the film, the monster is still absolutely terrifying. Tim Purcell had to sit through hours of makeup for this role. In some scenes, the folks in post-production used CGI to make his face even scarier.
