Horror High

1973 ·1h 25m · ★ 5.5 (35)

A nerdy high school super whiz experiments with a chemical which will transform his guinea pig "Mr. Mumps" from a gentle pet into a ravenous monster. In a fit of rage against his tormentors at the high school, Vernon Potts goes on a killing spree, eliminating all of those who ever picked on him - the Gym Coach, the School Jock, The Creepy Janitor & his hated teacher, Ms. Grindstaff.

Why it matters

A low-budget ’70s slash-and-transform flick where high school torment meets science-gone-wrong body horror, capturing that era’s uneasy teen outsider vibe.

  • Early hybrid of mad science and slasher tropes, predating the teen horror boom by years
  • Pat Cardi’s awkward, vulnerable lead grounds the monster-within story in authentic high school misery
  • Practical effects lean into gooey, creature-ish transformations that echo ’50s B-movie charm
  • For fans of retro regional horror and the uneasy melding of adolescent angst with monster madness
