Inception is one of the two best science fiction movies I've ever seen (along with Gilliam's Brazil) -- in fact, it's one of two sf movies that I'd rank with the very best sf novels.
Here's a YouTube clip showing some of the nice attention to detail in the film: the two major musical stings in the movie (a threatening, bassy throb and a grainy Victrola of Edith Piaf singing "Je Ne Regrette Rien") are, in fact, the same song, played at very different speeds.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
