Not a movie, but it's definitely SF:

> "Far Centaurus" (1944) by A. E. van Vogt: This classic science fiction story tells the tale of a group of colonists who embark on a centuries-long voyage to the distant star system Centaurus. Upon arrival, they discover that Earth has developed faster-than-light travel during their journey, and a thriving human civilization already exists in Centaurus. > > "The Songs of Distant Earth" (1986) by Arthur C. Clarke: The novel features the crew of a slower-than-light colony ship, Magellan, who arrive at their destination planet Thalassa, only to discover that faster-than-light ships have already colonized other planets in the meantime. The story explores the consequences of different levels of technology and adaptation for the human settlers. > > "Tau Zero" (1970) by Poul Anderson: In this novel, a group of colonists aboard the starship Leonora Christine set out to explore a distant star system. During their journey, they encounter a series of technical malfunctions that cause their ship to accelerate uncontrollably. As a result, they experience time dilation, and the rest of the universe rapidly advances around them. They must navigate their own obsolescence and search for a new home as other expeditions overtake them.
