Deadly Eyes

Deadly Eyes Also known as The Rats, Rats and Night Eyes is a 1982 Canadian horror film directed by Robert Clouse, very loosely based on the horror novel The Rats by James Herbert. It was also Golden Harvests only horror film. The story revolves around giant black rats who begin eating the residents of Toronto after ingesting contaminated grain.

Giant rats the size of small dogs living in mountains of grain full of steroids are rendered homeless when a health department inspector orders it burned. The Rats migrate to a suburban home occupied by unsupervised high school students. The Rats begin to kill a toddler left unattended in a high chair as well as a senior citizen, walking the snowy streets alone late at night. Scatman Crothers, who briefly plays a health department field inspector, is destined to become the next victim. Inspecting the bowels of the citys sewer system, he encounters a pack of rats. Scatman commences with the running of the rats in the sewer, followed by his demise.Paul telephones his friend, a professor who is a rat expert, who instantly concludes that the steroid feed had spawned a new breed of superrat that had migrated into the sewers in search of food. Upon hearing this information, the Health Inspector immediately orders the fumigation of the entire city sewer system, which is immediately and efficiently carried out with no apparent effect. The futility of this action is confirmed when the rat expert himself is attacked and killed. The Rats then move on to a bowling alley and a movie theater and make their first brazen mass attack on the unsuspecting public. The Rats select the viewers of a Bruce Lee movie, resulting in numerous deaths and a scene of fleeing film patrons. ........
