With "Tron: Legacy" director Joseph Kosinski's "Oblivion" only five months away from release, we haven't seen anything -- not even an image -- from the somewhat mysterious blockbuster. But that all changes on Sunday when the first trailer arrives. But until then, a rather tantalizing poster has arrived with Future Cruise looking at a waterfall between some "Inception"-d buildings. It's a pretty striking image, and one that does a good job teasing without giving up the game. Here's the synopsis: Jack Harper (Cruise) is one of the last few drone repairmen stationed on Earth. Part of a massive operation to extract vital resources after decades of war with a terrifying threat known as the Scavs, Jack’s mission is nearly complete. Living and patrolling the breathtaking skies from thousands of feet above, his soaring existence is brought crashing down when he rescues a beautiful stranger from a downed spacecraft. Her arrival triggers a chain of events that forces him to question everything he knows and puts the fate of humanity in his hands.
