Now a longer international UK trailer
"There's a good amount of spectacle on display in this international trailer from MSN UK, with more expansive visuals of the desolate Earth years after an attempted alien invasion. The basics of the story, with Cruise as terrestrial drone repair soldier and the rest of humanity in orbit, also get some attention. But this trailer is focused on the mystery at the center of the story, and gives a better sense of just what form the film's conflict takes. Also, we get out first real look at Melissa Leo in her physically detached role."
It is a 2:25 length trailer. It gives a bunch away. I wish it were only 45 seconds i would still go see it. I will still see it. Looks like a real scifi film.
