Before Kristen Stewart and Robert Pattinson can even begin their We Don't Give a Crap tour to promote New Moon, the studio has already started hunting for the co-stars of the third flick, Eclipse. Here's who they're looking for so far, according to the casting notice:

Riley "is a handsome, blond, clean-cut college boy who falls victim to Victoria," the notice reads. He's in his early to mid 20s and "plays an integral role in Victoria's attempt to murder Bella Swan." There are two more members of the Quileute tribe and La Push wolf pack in Eclipse. Like New Moon, they are looking for Native American or First Nations actors to fill the roles. "Seth Clearwater is a "tall, gangly-limbed boy with a huge, happy grin," the notice reads. "Seth idolizes Jacob." Seth's big sister is 19-year-old Leah Clearwater and the only female member of La Push: "She is tall and slender with beautiful skin and short cropped black hair. She would be considered gorgeous if not for the perpetual scowl she carries due to a broken heart and her anger issues."

Meanwhile, Taylor Lautner will continue to put on mass for the third film, after having put on around 30 pounds of muscle for New Moon. "Jacob's character is continually growing throughout the series," Lautner said at the MTV Movie Awards Sunday night, "so I got about eight weeks off before I go back again for Eclipse and I'm going to be hitting the gym." As for the fourth installment of the Twilight series, Breaking Dawn? The cast -- including Kristen, Robert, Ashley Greene and Peter Facinelli -- have all expressed interest in sticking around for a fourth. We are NEVER going to be done with this. Kristen Stewart is going to be stumbling down red carpets and dropping awards on the floor until we're all old and grey. Eventually, she'll just carry the bong up on stage with her. />  Before Kristen Stewart and Robert Pattinson can even begin their We Don't Give a Crap tour to promote New Moon, the studio has already started hunting for the co-stars of the third flick, Eclipse.
