【Just a Stranger】

LOS ANGELES -- The Just a StrangerMan in the High Castle used to have a more neutral office space.

Though the show doesn't return until Dec. 16, Amazon on Tuesday announced that Stephen Root will play the actor behind the titular role.

The show, developed by Frank Spotnitz, is based on the bestselling 1962 Philip K. Dick novel. Set in 1962, the dystopian series takes place in an alternate history in which the Axis powers won WWII.

Root, perhaps most known for his role as a nebbish corporate drone in Office Space, more recently starred in the comedy film Mike and Dave Need Wedding Dates. He's also had recurring roles on many popular TV shows including Fargo, The Big Bang Theoryand Boardwalk Empire.

In Season 1, the Man in the High Castle remained a mystery. But starting with the first episode of Season 2, he'll have a big presence.

Here's the full Season 2 synopsis via Amazon:

"The show resumes with Juliana Crain (Alexa Davalos) facing the consequences of her decision to betray the Resistance and allow Joe Blake (Luke Kleintank), a suspected Nazi agent, to escape the Pacific States with a film originally bound for the Man in the High Castle. Joe himself returns a hero to the Reich and finds himself thrust into the Nazi capital of Berlin, face to face with the father who abandoned him. Meanwhile, Frank Frink (Rupert Evans) becomes increasingly radicalized and drawn further into the resistance after seeing images of his own execution in the mysterious films.

With political tensions mounting between Germany and Japan, Trade Minister Tagomi (Cary-Hiroyuki Tagawa) begins to regret his success in smuggling nuclear technology from the Reich and seeks solace in the strange new world he discovered at the end of season one. Meanwhile, Obergruppenführer John Smith (Rufus Sewell) struggles to reconcile the values of the Reich with thedeteriorating health of his son— all while tasked with a mission from the Fuhrer for which failure is not an option.  And Chief Inspector Kido (Joel De La Fuente) begins to take greater interest in the Man in the High Castle, the films, and how Juliana Crain is connect."
