DVD & Blu-ray: Southern Comfort (15) Walter Hill DVD/Blu-ray (106mins)

Walter Hill is one of American's most underrated action directors and this deeply unsettling 1981 thriller, set in Louisiana's swampland, is one of the auteur's finest. A dysfunctional group of National Guardsman (including Powers Boothe and Keith Carradine) embark on a routine weekend exercise and end up being inexplicably picked off by a group of inscrutable Cajun hunters.
