It was reported in 2010 that Ridley Scott would produce an adaptation of "The Man in the High Castle" for the BBC, in the form of a mini-series. A pilot episode was released on Amazon Prime in January 2015 and Season 1 was fully released in ten episodes of about 60 minutes each on November 20, 2015. 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 to be released in 2018. In July 2018, it was announced that the series had been renewed for a fourth season.
