Based in the early 14th century, Knightfall offers a fictionalized take on the persecution of the Knights Templar, a Catholic military order closely linked to the Crusades. The historical drama is centreed on Templar leader Landry du Lauzon, who's played by Downton Abbey's Tom Cullen, and with much of the filming done in Croatia, you'll definitely be getting some major King's Landing vibes.
