If you thought the poster for Jennifer's Lawrence psychological thriller Mother! was creepy, just wait until you see the full trailer. Lawrence's character attempts to "breathe new life" into her home before strange things start happening when she and her husband (Javier Bardem) let unexpected guests stay over. We're talking actual blood dripping from the walls, people. Are the hallucinations all in her head, or is it something else entirely? Since the film's writer and director, Darren Aronofsky — who is dating Lawrence in real life — is the same person responsible for Black Swan, we can only imagine what's in store. Catch the trailer above before it hits theaters on Sept. 15.
