**_A high school graduation party at a mansion in Wichita is invaded by killers_** Shot in the spring of 1986, this is a cheap slasher with no-name actors that inexplicably begins by throwing in scenes from “Graduation Day” from five years earlier. That slasher is more all-around entertaining compared to this. It thankfully includes the expected staples of the genre, plus throws in a decent (albeit unbelievable) twist at the end, but the main villain is hammy and unconvincing, not to mention the proceedings are generally dull. The script needed a rewrite to flush out interest. So “Night Screams” is obscure for good reason. Still, I’ve seen worse. It runs 1 hour, 25 minutes, and was shot in Wichita, Kansas. GRADE: C/C-
