The trailer for the third Twilight movie is out, and the Eclipse vampire war is on. What are the biggest changes? Bryce Dallas Howard has taken over the role of red-headed Victoria and Jacob has some new shorts!

Lots of pining and flower-field-sitting happening in the new Eclipse trailer. But we have to admit, it's really odd to see Bryce Dallas Howard take over for Rachelle Lefevre, especially since the fans really went to the mattresses for Jacob when rumors that he was being replaced surfaced, pre-New Moon. We'll have to wait to see more to judge how she handles being a general of a new vampire army. And second, Jacob has finally ditched the tragic jean-sshort look for cargo shorts. But will they shatter like his old, wolf-transformation-friendly pants of yore?

Eclipse will be in theaters June 30th.
