Logan's Run is a 1976 American science fiction action film directed by Michael Anderson and starring Michael York, Jenny Agutter, Richard Jordan, Roscoe Lee Browne, Farrah Fawcett, and Peter Ustinov. The screenplay by David Zelag Goodman is based on the 1967 novel Logan's Run by William F. Nolan and George Clayton Johnson. It depicts a future society, on the surface a utopia, but soon revealed as a dystopia in which the population and the consumption of resources are maintained in equilibrium by killing everyone who reaches the age of 30. The story follows the actions of Logan 5, a "Sandman" who has terminated others who have attempted to escape death and is now faced with termination himself.

Science fiction is a film genre that uses speculative, fictional science-based depictions of phenomena that are not fully accepted by mainstream science, such as extraterrestrial lifeforms, spacecraft, robots, cyborgs, mutants, interstellar travel, time travel, or other technologies. Science fiction films have often been used to focus on political or social issues, and to explore philosophical issues like the human condition.
