“Hell and Back Again,” a documentary by photographer Danfung Dennis, begins hitting theaters Oct. 5. It features members of Echo Company, 2nd Battalion, 8th Marines, out of Camp Lejeune, N.C., who deployed to Afghanistan in 2009. Arguably the most powerful scenes in the trailer involve 27-year-old Sgt. Nathan Harris’ transition back home. The trailer is posted below. For the screening schedule click here. I’ll be buying a ticket. [vimeo]http://vimeo.com/29165748[/vimeo]
