"Logan's Run" explores utopian and dystopian themes, with the idea that characters willingly die instead of reaching advanced ages, reflecting the idea that "Utopias require its participants to give something up in order to create harmony and uniformity".Common dystopian themes include an evil ruling authority, the confiscation of children from parents, life in a city, and the idea of human overpopulation, in this case causing the protagonists to leave the urban environment.
