Carey Mulligan, interviewed on Collider.com. The previous paragraph gives away the premise of Never Let Me Go, the film (adapted from the Kazio Ishiguro novel) in which she stars next.
For me, that process Mulligan describes - not quite understanding the world in a book, but discovering what it is that makes it different - is a huge part of the joy of science fiction. Sure, a lot of people think that it involves “space suits and aliens” (as Mulligan says in the same paragraph), but the best work doesn’t involve that at all.
(Having said that, I never did finish the novel; it spent a bit too much time with characters as characters, rather than action as a character, to abuse a quote from An Education.)
