In an email to the movie's online backers, sent out on July 16, Zach Braff revealed that Greene has been brought in as a replacement, reports contactmusic.com. "Well, since you're having your first shot as being (a) movie producer, it's time you experience something that happens a lot: Scheduling conflicts," he said in the mail.
"We've tried our hardest, but we've been unable to figure out the lovely Anna Kendrick's scheduling conflicts with another movie she's doing... You may know Ashley from Twilight. I've known Ashley for a couple years now and I'm so excited she's accepted my invitation to join our Kickstarter Klub (sic).
Zach Braff used crowd-funding website kickstarter.com to raise $3.1 million in donations to make the film, which is a sequel to his 2004 movie Garden State. Talking further about Ashley, he added, "Not only is Ashley gorgeous and charming, but she is hilarious, a very good actress and normal and cool and we are so lucky to have her."
