Three are dead. Who is number four? From director D.J. Caruso (Disturbia) and producer Michael Bay (Transformers), comes this gripping, action-packed thriller. John Smith (Alex Pettyfer) is an extraordinary teen masking his true identity to elude a deadly enemy sent to destroy him. Living with his guardian (Timothy Olyphant) in the small town he now calls home, John encounters unexpected, life-changing events - his first love (Dianna Agron, TV's Glee), powerful new abilities and a secret connection to the others who share his incredible destiny. Complete with deleted scenes and more, "I Am Number Four" is an explosive, suspense-filled ride that will take you to the edge of your seat and beyond.
