Are they really changing Alice Cullen in Breaking Dawn?

i heared about it too
but i just Amore this alice
she's sweet and so... funny
idk
they would be noobs to do this

Everyone thinks that she leaves because they have no chance of winning the fight against the Volturi when they come to destroy Renesmee, and that when they lose, Aro will want to make her part of the Volturi. The real reason she leaves is so that she can try to find another half human, half vampire in South America so that they will be able to find out for certain how Renesmee will turn out. She didnt tell anyone of this reason because she didn't want Aro to find out and she needed them to believe that they had no chance of winning so the Volturi wouldn't know that they had anything else up their sleeves to trick them.

Do te mean changing the actress for the film breaking dawn?

If te do; its true there was an issue with ashley greene and kellan lutz (alice an emmett) and their contracts as they were both wanting più money for their roles. However they have both officially been confirmed and have signed contracts so there will be no actor changed in BD
