Shadows Run Black  (1985)

Theatrical Release Information:
Shadows Run Black

In this exploitational slice-n-dicer masquerading as a police thriller, a college coed can do nothing while all her friends are being murdered by mysterious man wielding a meat cleaver. In true exploitational style, most of the women are killed in various states of undress and are not even assigned character names other than things like "Girl Stabbed in the Kitchen." A zealous cop begins investigating the case to stop the bloody butcher of bosomy babes. Look closely and you will see that the serial killer is played by a young Kevin Costner. ~ Sandra Brennan, All Movie Guide
