Wolfen Trailer (1981)
Trailer for Wolfen. A real estate tycoon, his coke-binging wife and a slum wino have something grisly in common: they're the latest victims in a series of random murders. A veteran NYPD detective soon suspects the killings may be supernatural and deliberate: ages-old beings of cunning intelligence and incredible power, defending their turf from the encroachments of humankind.
