'The Hateful Eight' is a 2015 American Western thriller film written and directed by Quentin Tarantino. It stars Samuel L. Jackson, Kurt Russell, Jennifer Jason Leigh, Walton Goggins, Demián Bichir, Tim Roth, Michael Madsen, and Bruce Dern as eight strangers who seek refuge from a blizzard in a stagecoach stopover some time after the American Civil War.

The original score was Italian composer Ennio Morricone's first and only for a Tarantino film, his first complete Western score in 34 years, and his first for a high-profile Hollywood production since Brian De Palma's 'Mission to Mars' in 2000.
