A trailer that refuses to show an image for 48 seconds is probably up to something good. The film is Don’t Be Afraid of the Dark (Miramax, 1.21.11), and you can sense right away that it’s a cut or two above. The news of Guillermo del Toro having produced and co-written is like a five-star review from Consumer Reports. The director is Troy Nixey. The costars are Katie Holmes, Guy Pearce, Bailee Madison, Alan Dale, Eliza Taylor-Cotter, etc.
