Happy Birthday to Me (1981)

What better way to celebrate a birthday than with an obscure birthday-themed slasher flick from the 80s? That's right, your host is another year older, but giallo-inspired movies about a killer at a prep school will never go out of style. Come for the red herrings and quirky characters, stay for the absoludicrous twist ending that was a clear inspiration to Kevin Williamson's 'Scream'!
