This is the reason insects can never get very big. Recent research, apparently, shows that at times the Earth's atmosphere has had a much higher oxygen cntent than it does now. These are the periods when larger insects were able to flourish.
But the giant insects of SF films would generally be impossible, even in a pure oxygen atmosphere, unless they used a completely different method of respiration. And then they wouldn't be true insects any more...
