I saw this movie back in the early 90’s. It is a horror movie I saw in the early morning one Christmas Eve. If it helps, it was on HBO I believe and the movie Witches came on right after. One of the scenes near the end of the movie showed a violent struggle between two characters. One character of African American descent had a small handheld electrical saw (it looked like a cast saw) taken to the back of his head and blood began to spew from his mouth. I believe the scene took place in an old hospital. Please help.
