Movie trailers can be found in the bonus screens of most DVDs. Rare is the case when the clips are the featured attraction, and a feature film is the extra — as in "Trailers from Hell! Volume Two."
In general, I prefer the films of Guillermo del Toro that he doesn’t direct (“The Orphanage,” “Splice”) to the ones he does (particularly “Hellboy” and its sequel). That pretty much holds true for “Don’t Be Afraid of the Dark,” which he only co-wrote and co-produced, ceding the director’s chair to newcomer Troy Nixey.
