Frightmare (1981)

Frightmare (1981), also known as The Horror Star, follows a group of drama students who tampered in god's domain. Following the death of their favorite horror movie star, the Vincent Price-esque Conrad Radzoff (Ferdy Mayne), a group of seven best friends and fellow drama students at the local university decide to sneak into the cemetery at night and abduct his corpse. Naturally, it isn't long before Conrad's corpse is reanimated and begins to pick off our randy twentysomething teenagers one by one! 

It's truly tragic that Donna McDaniel's Donna and Alan Stock's Oscar didn't know that they were in a slasher movie and decided to have sex, sealing their fate! Luckily for us, we get to see Donna McDaniel topless before she meets that untimely end, which is all you can really hope for from a movie like this!
