Three years ago, most people had never even heard the names Robert Pattinson, Taylor Lautner, and Kristen Stewart. Today, the three stars of “The Twilight Saga” are international celebrities that attract a frenzy of extremely passionate fans wherever they go. Their faces are plastered on movie posters and magazine covers that promise to reveal intimate details of Pattinson and Stewart’s real-life romance. Paparazzi are tracking their every move as they gear up for the release of “Eclipse,” the third movie based on Stephanie Meyer’s best-selling books. This film will have teenage girls and their mothers circling movie theatres on June 30th like bloodthirsty sharks (or vampires), and you'll be hard-pressed to find a single one who isn't able to name the actors who play Bella, Edward, and Jacob on-screen. What a difference a few vampire movies can make!
