We've learned from "Twilight: Eclipse" director David Slade that several of the cast members for Summit Entertainment's third installment in their vampire saga have all completed their scenes. Elizabeth Reaser, Kellan Lutz, Taylor Lautner and two other actors all finished filming yesterday. Slade hosted a wrap party for the film and while the movie isn't entirely finished shooting, Slade wanted the entire cast to be of attendance. Oddly, Kristen Stewart was absent. We're not exactly sure why the leading lady didn't make an appearance, but on a positive note, Robert Pattinson did. "Twilight: Eclipse" hits theaters next June. You can check out "Twilight: New Moon" in theaters next month.
