Fiend (1980)

An alien energy reanimates a corpse who rises from the grave, kills a couple, buys a house, gets a car, feeds his cat, opens a music academy, and teaches violin. Honestly, is there a more bizarre concept for a film? What sort of reanimated corpse is going to buy a house or teach violin? And where did he get the money to purchase the home in the first place?

The corpse, who goes by the name of Mr. Longfellow, has to kill to keep his body from deteriorating. He strangles women in the neighborhood and glows red when he's committing these crimes. He spends all his time down in the basement rec room. In the other half of the basement, there is a little area where he keeps a knife in fancy box and slashes photographs of his victims.

Mr. Kender, his next door neighbor, suspects something is off with Longfellow, especially after a little girl is murdered behind their home. When Longfellow needs to kill, he starts looking waxy and his eyelids get all droopy which is yucky.

While the story is ridiculous, the film is actually well done, nicely edited and another good attempt by Don Dohler.
