Serenity is a 2005 science fiction western genre film. It is set in the universe of the canceled FOX show, FireFly. It’s the story of a caption and a crew of a transport and cargo ship. The caption and first mate were veterans of the losing side of the Unification War, who now lived a life of crime. Though that was interrupted by a psychic passenger who carries a dangerous secret. Serenity mixes genres by being set 500 years in the future and using very technological devices, but the war and the plot is said to be influenced by the post American civil war period. The setting also looked futuristic but very deserity. The director also used the Wild West style of drab earth tone clothing.
