J.T. Petty, horror filmmaker (Soft for Digging, The Burrowers) and husband of Sarah Langan, has directed a trailer for Langan's just-released novel Audrey's Door. It's very effective: slowly building and disquieting for most of its 2-minute, 22-second runtime -- then downright terrifying at the end! For maximum effect, watch it alone. I've still got tingles running down my spine.
