Bug (1975)

If you enjoy scary movies about killer insects, then you'll love Bug, from 1975. An earthquake releases a strain of mutant cockroaches with the ability to start fires. Eventually most of the bugs die because they cannot survive in the low air pressure on the Earth's surface, but a scientist keeps one alive in a pressure chamber.
