The current sky advert with Sir Ben Kinsgley spoofing Kipling's "if" finishes with a a few clips of film, does anyone know who the actress is in the last of those and what film it's from?
If we're thinking of the same clip, I'm pretty sure it's Anna Paquin (from "The Piano" and the "X-Men" movies). I don't know which film, though; I'd guess at "25th Hour" or possibly "Buffalo Soldiers", but haven't seen either.
