At the end of the film someone calls with a question: what is the weight of the entire Earth. Technically that's unanswerable. One might calculate the mass of Earth but weight depends on the force of gravity, so a person might be 110 lbs on Earth but would be only 18 lbs on the Moon. Since the Earth isn't sitting on another planetary body there is no concept of weight, only its mass. Of course back in 1957 people might not have been such sticklers for this distinction.
