The Man in the High Castle is an American dystopian alternative history television series produced by Amazon Studios, Scott Free Productions, Headline Pictures, Electric Shepherd Productions and Big Light Productions. The series is loosely based on the 1962 novel of the same name by science fiction author Philip K. Dick. In the series' alternate version of 1962 America, the Axis powers have won World War II and divided the United States into two puppet states: the Greater Nazi Reich and the Japanese Pacific States. The series follows characters whose destinies intertwine after coming into contact with a series of propaganda films that show a vastly different history from that of their own.
Premiering in January 2015, the pilot was Amazon's "most-watched since the original series development program began." The next month Amazon ordered episodes to fill out a ten-episode season, which was released in November, to positive reviews. A second season of ten episodes premiered in December 2016, with a third season announced a few weeks later.
