Charlie Bewley said the shoots were very different from the scenes they shot in Italy for New Moon. "There were 12 frowned, soaking wet movie stars sitting in the green room," and he said the photo op there would have been a "paparazzi dream."

There were two new additions to the cast that RadarOnline.com spoke with at the premiere. Kirsten Prout and Jodelle Ferland, who plays the newborn vampire Bree and who said she really enjoyed filming scenes with Rob Pattinson. "He's definitely not Edward Cullen," she dished. "Edward is so serious, he's a really cool guy!"
