Ever since I met a group of Twilight Moms waiting in line at Comic-Con I have been intrigued by the new teen vampire film. Based on a successful series of books, Twilight has moms and their young daughters in a mad frenzy for the film. Here's the second trailer. the film opens on Friday with fans probably already starting to line up (or at least buying their tickets) for the Thursday midnight show. Trailer courtesy of Summit films.
