It’s been more than a year since audiences got their first peek at Alfonso Cuarón’s upcoming astronaut thriller Gravity—but with the release of two new trailer clips, giddy fans are screaming for more. Or maybe they’re just screaming.

Sandra Bullock and George Clooney play astronauts, and a space-debris collision leaves them drifting unanchored in space, with limited oxygen and no contact with the planet to which they’ll attempt to return. The trailer won raves when it debuted at Comic-Con and now everyone can see why: Cuarón uses a single scene and uninterrupted camera work—a skill the director showed off with long takes in Children of Men—to give the trailer both suspense and artistic heft.
The only gripe viewers seem to have thus far is whether the movie is committing the sci-fi no-no of sound in space. (Our take: no, that sound is inside their helmets, from microphones.)
