Michael and Shawn Rasmussen wrote, and the legendary John Carpenter directs The Ward, Warner Bros. terrifying new thriller about a malevolent ghost terrorizing a young woman trapped in the basement of a mental institution. The full-length trailer for The Ward has finally arrived on-line, and you can check it out in the clip below along with two new poster images:

When an old farmhouse is set ablaze by Kristen (Amber Heard), a distraught young woman, she is taken by police to the North Bend Psychiatric Hospital. She awakens in a special ward with four similarly unbalanced and wayward girls: Sarah (Danielle Panabaker), a flirty and sass-talking know it all; Iris (Lyndsy Fonseca), a sensitive and talented artist who tries to make her feel welcome; Emily (Mamie Gummer), a reckless but playful outcast; and Zoey (Laura-Leigh), who hides behind a childlike persona and her beloved stuffed bunny. Kirsten's therapist, Dr. Stringer (Jared Harris), tries to uncover the root cause of her breakdown, but despite his calm and understanding manner, she resists any attempts at help and rehabilitation. Unfortunately, the hospital is not the sanctuary it seems to be. Kristen begins to have strange run-ins with a shadowy phantom who roams the halls when the ward is locked down at night. Persistent and inquisitive, she goes digging for information about former patients and soon becomes convinced that no one ever leaves the ward alive.
