Not sure how to describe these movies: Shoot ‘Em Up, Swiss Army Man,
Movies that the pitch to hire the actors must have been “You are ridiculous and say some crazy shit, but you believe with every fiber of yourself that you are right”. Where the delivery is deadpan and the actors are not aware they are in a comedy. (Yes I know that is not possible, but no winks to the camera and acknowledgement that they are in some kind of dark humor).
