Trivia, insights & behind the scenes
David A. Prior shot this in 1983 on consumer-grade video equipment, making it one of the earliest shot-on-video slasher films. The entire budget reportedly wouldn't cover a modern iPhone.
Sledgehammer became a VHS rental legend precisely because it looked like homemade snuff, helping define the 'SOV horror' aesthetic that influenced filmmakers like Ti West decades later.
