We've already told you about the hot trend of Youtube trailers for books, and now it's going to the next level - a book trailer chosen by Stephen King will appear in movie theaters.

Okay, so it's only a couple of theaters: at a New York city movie premiere and in the winner's hometown. But that's still pretty awesome. The trailer must be a promo for a book published by Shomi, an imprint of Dorchester that publishes books combining fantasy, science fiction, cyberpunk, thrillers and romance. To enter the Shomi contest, upload your trailer to Youtube. Before you start pitying Stephen King for having to sit through tons of trailers for cyberpunk time-travel romance novels, be reassured: he only has to watch the five finalists, as chosen by Shomi. Presumably he'll be judging them against the high standards of his own directorial debut. [Galleycat]
