"I feel like the difference on the third one is that we all are so used to going back to this story that we fell right back into it", Stewart told Cinematical"... We were so comfortable with these characters that we have established a dynamic with the cast and the producers, and we would just sort of do our thing."Fanning says she spent about three days working on each installment of the Twilight Saga franchise, appearing at the end of filming in both New Moon and Eclipse.
