IO9's produced a science fiction film physics report-card that evaluates the accuracy of the physics in a large number of top-grossing sf films. Basically? They all stink. Link
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.
