Now there’s a new Man in the High Castle trailer, showing off some of the fresh footage for episodes beyond the pilot.

That trailer highlights one of the big changes from the book, which anyone who saw the pilot has already seen. In the original novel, The Grasshopper Lies Heavy is a revolutionary book that depicts life more or less as we know it — an America ruled by Americans. It’s a book that gives the characters hope.

Here, that document is a film. It’s a potentially canny change that makes its contents easier to show us, the viewers, but also turns the document into something that can’t be passed along and picked up as easily as the book in Dick’s original novel. That change is one of the elements we’re most curious to see played out in the series when further episodes debut.

Based on Philip K. Dick’s award-winning novel, and executive produced by Ridley Scott (Blade Runner), The Man in the High Castle explores what it would be like if the Allied Powers had lost WWII, and Japan and Germany ruled the United States. Starring Rufus Sewell (John Adams), Luke Kleintank (Pretty Little Liars) and Alexa Davalos (Mob City).
