The Last House on the Left (1972)
The Last House on the Left is a 1972 American exploitation-horror film written, edited, and directed by Wes Craven and produced by Sean S. Cunningham. The story is inspired by the 1960 Swedish film The Virgin Spring, directed by Ingmar Bergman, which in turn is based on the 13th-century Swedish ballad "Töres döttrar i Wänge". It is the directorial debut from Craven.
