Nice butt in Oblivion
I loved her butt in Oblivion it was amazing! She is such an amazingly sexy actress.
Its too bad we couldn't have seen more!
If it was a famous American actress, then yes they might use a body double. But this is a relatively unknown British actress, so why would they in this case?
