The pilot episode of Amazon's The Man in the High Castle was originally released on 15 January 2015 on their Prime web video streaming service as part of the company’s first pilot season of 2015.
Due to its success, Amazon announced on February 18 2015 that a full season would be produced. This full season was released on 20 November 2015, with the first two episodes being available during a preview weekend starting 23 October 2015.
The pilot and episode 2 will be available for no-charge at http://www.amazon.com/maninthehighcastle beginning at 12 AM PST on Friday, October 23rd and ending at 11:59 PM PST on Sunday, October 25th in the U.S. and UK. Following the Preview Weekend, the show’s second episode will available exclusively to all Amazon Prime Members, prior to the season launch of all episodes on November 20th.
Are there any differences between the pilot episode released in January versus the one that is part of the full season?
