Time Travel Movies Worth Untangling

Begin with Back to the Future for a clear cause-and-effect adventure, Palm Springs for a shared loop, or Beyond the Infinite Two Minutes for a tiny premise that keeps expanding. Timecrimes, Predestination and Primer ask for increasingly close attention. This selection includes bodily journeys, repeated intervals and films where messages or images cross time instead of people. Their rules vary: a closed loop, a changeable history and a speculative simulation invite different questions. The reward can be emotional as well as diagrammatic, and some films deliberately leave limits unexplained. Descriptions identify the kind of puzzle without mapping its solution.
