The Last Man on the Moon (2014)

Gene Cernan — Apollo 17 commander and the last human to walk on the Moon in December 1972 — tells his story with devastating honesty. The film doesn't shy away from the personal cost: a marriage destroyed by the all-consuming astronaut life, a daughter who grew up without him, the guilt of choosing the Moon over his family. Cernan returned to the lunar surface decades later (in his mind) still haunted by the promise he made to his daughter to write her initials in the lunar dust. He did. They're still there.
