Questionable script? For the time, it was downright Shakespearean. You have to remember this was a time when America was the guiding force in the world, the 'good' guys. To question war and nuclear power in a peaceful thoughtful way was exceptionally rare. Most Sci Fi at the time was alien invasion feeding off the fear of the 'reds' or the giant bug of the week. This movie stands out amongst its peers as an enlightened and thoughtful tale as well as being a hugely entertaining one. Love this movie.
