Trailer Premiere: Watch Michael Shannon And Amy Ryan In 'The Missing Person'

Writer/director Noah Buschel made a name for himself with "Neal Cassidy" and "Bringing Rain," and now he's back again for "The Missing Person." The film -- which will have its world premiere at the forthcoming Sundance Film Festival -- stars Amy Ryan, and Michael Shannon (fresh off his much talked-about "Revolutionary Road" performance) as a private detective hired to follow a mysterious stranger (Frank Wood).

The twist? The guy's listed as having been killed in the 9/11 attacks. With a reward offered for returning the man to his wife, Shannon's character must decide whether to bring him in or turn him loose. Check out the first trailer and the film's poster debut after the jump.
