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.

" You're very human. "

a bullied biology nerd drinks his own Jekyll & Hyde serum and turns into a hairy monster to get revenge.
It's pure early 70s drive in sludge.
the makeup is cheap , the acting is worse , and it spends way too long being boring for about three decent kills.
It has that grimy 1973 vibe that cult fans love , but as a movie it's slow and pretty mean spirited without being fun.

Slaughter High stole this film's nachos and reheated it in a high-quality oven.

A really cool 70s slasher-esque version of Jekyll And Hyde. Didn't impress me much but i was never too bored.

Also the kill with the spiked shoes was so fucking rad and creative!
