Wish I Was Here Trailer

The first trailer for Zach Braff's new movie has been released and I'm still not fully certain I know what it's about. Although, it seems fairly interesting and it's one of those films with heart, at least that's what I see from the trailer. Also in the movie is Josh Gad, Mandy Patinkin, and (oh hell yeah) Donald Faison! Plus, Zach said in the background of one of the scenes is Rowdy, the stuffed dog from Scrubs. I'm interested!
