Science fiction movies serve as directional indicators for the winds of the zeitgeist. In the 1950s we were served up cautionary tales about the misuse of science. We fooled with atomic energy and got gigantic spiders, a 50-foot woman, an Incredible Shrinking Man—and, of course, Godzilla. We were meant to take away from these films a sense that we shouldn't muck about with the natural order or play God.

With no creator there are no creatures, only organisms.

The universe will let us know—later—whether or not Man has any "right" to expand through it.
In the meantime the [Mobile Infantry] will be in there, on the bounce and swinging, on the side of our own race.

As the film begins, they have just wiped out Buenos Aires in a surprise attack. Whereas in the novel, the Arachnids use advanced weapons and space ships, director ...
