Warner Bros. Pictures have unveiled the first teaser trailer for M. Night Shyamalan's upcoming film, Lady in the Water, starring Paul Giamatti, Bryce Dallas Howard, Freddy Rodriguez, Jeffrey Wright, Bob Balaban, Sarita Choudhury, Mary Beth Hurt, Cindy Cheung and Joe Reitman.

In Lady in the Water, a story originally conceived by Shyamalan for his children, a modest building manager named Cleveland Heep (Paul Giamatti) rescues a mysterious young woman (Bryce Dallas Howard) from danger and discovers she is actually a narf, a character from a bedtime story who is trying to make the treacherous journey from our world back to hers. Cleveland and his fellow tenants start to realize that they are also characters in this bedtime story. As Cleveland falls deeper and deeper in love with the woman, he works together with the tenants to protect his new fragile friend from the deadly creatures that reside in this fable and are determined to prevent her from returning home.
