The Texas Chain Saw Massacre (1974)

In director Tobe Hooper's seminal horror film:

• the sudden appearances of Leatherface (Gunnar Hansen) wearing a butcher's apron and a mask stitched out of human skin wielding a roaring chain saw
• the shocking scene of Leatherface in the farmhouse emerging from behind a sliding door when he sledge-hammered Kirk's (William Vail) head
• the shocking moment that Pam (Teri McMinn) was hung by her upper back on a meat hook
• the scene of sole surviving Sally Hardesty (Marilyn Burns) being held captive at the cannibals' dinner table (and having her finger cut as an appetizer for the weakened, withered, vampiric and patriarchal Grandfather (John Dugan))
• the film's climax as Sally escaped in the back of a pickup truck and left the buzzing, chainsaw-wielding killer standing on the highway behind her, spinning and twirling in the golden light
