If you've ever wanted to be an astronaut, or even just find a way to travel space as a civilian, it appears as if this Gravity trailer is trying to discourage that.
Despite the grand scale of this scene, the most impressive part of this Gravity trailer is that it is one continuous shot. Don't believe me? Watch it again - all one shot.
Director Alfonso Cuaron is known for his long shots but this just seems even more of an achievement given the spinning and the panic, and well, it's in "space".
We've seen the stars, George Clooney and Sandra Bullock, in this Gravity image and apparently those are the only two faces we will see in the film. There are other voices, as heard in the trailer, but Clooney and Bullock are the only faces on screen. Luckily those two faces are easy on the eyes.
Even if our eyes might be shielded as our stomach drops to our toes at the idea of spinning alone through space.
