The director George P. Cosmatos creates a new subgenre of rat thriller with Of Unknown Origin.
I was drawn to this Canadian-American movie shot in Montréal due to it featuring Peter Weller (of the later Robocop fame), as well as its ominous title. The movie never quite lives up to its premise, and turns into monotonous mouse and cat game where Weller gets fixated on getting rid of a rodent and ends up destroying both his house and him family along the way.
It is not very scary, not that much fun and gets pretty old pretty fast. The concept could have probably worked better as a 20-minute Simpsons episode instead.
