Earlier this month, Universal Pictures debuted the first trailer for Oblivion, starring Tom Cruise as Jack Harper, one of the last men on Earth. The story takes place in the future, where all of humanity lives in sky cities after the planet has become too toxic to live on. Jack is tasked with repairing the drones that extract vital resources in the aftermath of a brutal war. His whole world is upended when a female pilot crash lands, and takes Jack on a journey of discovery that forces him to question everything he has known to be true. Today, the studio has debuted the trailer with a commentary track by director Joseph Kosinski (Tron: Legacy), which sheds even more light on this sci-fi thriller.
