The Dry Land is a new movie about a soldier's battle with PTSD. Here's the movie's website, where you can watch a trailer and find out if it's playing in your area. (It opens in different cities every few weeks after the initial July 30th release in LA and other top markets.)
Also worth reading: the producers' blog, where they write about the film and how people are reacting to it.
The film has already screened for some military and veterans' groups. If you've seen it, let us know what you think!
