In Time is a 2011 American dystopian sci-fi thriller film written, directed, and produced by Andrew Niccol and starring Amanda Seyfried and Justin Timberlake. In 2169, people are born genetically engineered with a digital clock on their forearm. When they turn 25 years old, they stop aging and their clock begins counting down from one year; when it reaches zero that person "times out" and dies instantly. Time has become the universal currency; it is used to pay for day-to-day expenses and can be transferred between people or capsules. The country has been divided into "time zones" based on the wealth of the population. The movie focuses on two specific zones: Dayton, a poor manufacturing area where people live day-to-day, and New Greenwich, the wealthiest time zone.
