Sometimes you should just leave a talking skull well enough alone. Actually, you should probably always leave a talking skull well enough alone, but that’s not exactly what I was getting at. I’m thinking of Bob from Jim Butcher’s Harry Dresden novels, and the unfortunate transformation he underwent in the tv adaptation, The Dresden Files. In the books, Bob is an incorporeal spirit trapped in a human skull. He’s sarcastic, amoral and lecherous, and has a fondness for trashy romance novels. In The Dresden Files, he’s a poncy British guy in a black suit who materializes out of a skull like some kind of genie butler.
