Watch 'Twilight' Star Elizabeth Reaser's New TV Series Online

Elizabeth Reaser is a busy actress: The former "Grey's Anatomy" star has an all-new romantic comedy, "The Ex List," premiering Friday night on CBS, and this November she's in one of the most anticipated movies of the year -- 'Twilight'! Tonight, Elizabeth's on the new ET set to talk love and vampires with our own Mark Steines. "I had no idea the extent of this fan base and how excited they are," Elizabeth tells Mark of the book-turned-movie. "My dad is a substitute teacher in a high school in Michigan and he's with kids all the time, and he says, 'It's really big time.' According to him, he has a lot more clout in school now, so that says a lot." In the movie, Elizabeth plays Esme Cullen, a member of the Cullen clan who is a vegetarian vampire, or what Elizabeth calls, "a conscientious vampire."
