Seriously. Before you watch this trailer for Alfonso Cuarón’s Gravity take a great big gulp of air, because I made the mistake of not doing that and caught myself holding my breath through the whole thing. You’re in for a treat with this one. New footage abounds. So get ready. Inhale.

And exhale. Whew. Intense.
