The ShoWest motion picture industry convention begins today and a teaser poster for The Golden Compass movie has been snapped by IESB.net. The poster features a glowingly-lit alethiometer, with the tagline (word-for-word from the book) of “It is the alethiometer. It tells the truth. As for how to read it, you’ll have to learn by yourself.” The poster also reaffirms the movie’s release date: December 7th, 2007. That’s a little under nine months today. Thanks to Dustin for the tip. View the poster.
