A couple of years ago I read this Primer on director Walter Hill, but I just recently got around to seeing Southern Comfort (1981). To begin with three of the leads are Keith Carradine, Powers Boothe, and Fred Ward--three great actors with charisma. The story is pretty interesting as well, a group of National Guardsmen on maneuvers in the Louisiana swamplands tangle with some locals and soon the film resembles John Boorman's Deliverance. That is until it becomes a Vietnam allegory more like Platoon. It also features a great soundtrack with Hill's first collaboration with Ry Cooder.
