Gravity premiered at the London Film Festival last night, and trust us, it's so amazing we can't even speak. Sandy plays a rookie medical engineer on her first ever space mission, joined only for a few moments by co-star George Clooney. But, boy, you won't be bored – not even for one minute. And to think, the role was first meant to go to Natalie Portman or Scarlett Johansson. Pssh, Sandy, you were perfect and here's why we <3 you!
