Kamikaze (1986)

French movie; grumpy scientist Michel Galabru is fired from his job, he takes to exploding the heads of television presenters from his nephews attic with an ultrasonic weapon he invented and can fire from his TV. Much of the movie involves the investigation into the murder spree and it is all treated very matter of fact and realistic. I couldn't help but think of the implications to the world of the movie from the madman's invention; live broadcasting would essentially have to end, in fact it would be so dangerous that it would probably become a crime. Unique and compelling feature. ***1/2
