New Art on Official Star Trek Site
----------------------------------
We mentioned yesterday that Paramount Pictures will
be handing out four posters at next week's San Diego
Comic-Con that when combined make up the official
teaser one-sheet. Now, the official site for J.J.
Abrams' Star Trek has been updated with high-quality
downloadable versions of the four posters. Don't
miss them!
