After a two-year hiatus, The Man In The High Castle, the alternate history, Axis-powers-won-World War II drama, returns to Amazon Prime on October 5. Set in the fictional Greater Nazi Reich, the show has never exactly been shy about about its use of Nazi imagery—remember those MTA ads? For members of the cast, the constant barrage of such symbolism can cause an unfortunate familiarity with Nazism. In a recent set visit, we talked to three Man In The High Castle stars—Chelah Horsdal, Rufus Sewell, and Bella Heathcote—about becoming familiar with Nazi imagery and resisting immunity to it.
