David Samuel "Sam" Peckinpah (February 21, 1925 – December 28, 1984) was an American filmmaker and screenwriter who achieved his status following the release of his 1969 Western epic The Wild Bunch. He became one of the major filmmakers of the 1970s, with his innovative and explicit depiction of action and violence, as well as his revisionist approach to the Western genre.

Peckinpah's films generally deal with the conflict between values and ideals, and the corruption of violence in human society. He was given the nickname "Bloody Sam" due to the violence in his films. His characters are often loners or losers who desire to be honorable, but are forced to compromise in order to survive in a world of nihilism and brutality.

Peckinpah's combative personality, marked by years of alcohol and drug abuse, has in many ways overshadowed his professional legacy. Many of his films were noted for behind-the-scenes battles with producers and crew members, damaging his reputation and career during his lifetime. Several of his films, including The Wild Bunch (1969), Straw Dogs (1971), Pat Garrett & Billy the Kid (1973) and Bring Me the Head of Alfredo Garcia (1974), remain controversial to this day.
