Alfonso Cuaron's latest Gravity trailer will knock the wind right out of you. The simple two-minute clip — made entirely in one take — shows what happens when things fall apart for George Clooney and Sandra Bullock in space. It is simply stunning. Earlier this year The Film Stage revealed that Gravity only has 156 shots in its two-hour runtime. Including the opening scene which will be an unbroken 17-minute shot. Which is exactly what you're getting a sneak peek of right now.
