Knightfall is based on true stories from the early 14th century, following the persecution of the Knights Templar, a Catholic military order linked to the Crusades, who have since become the subjects of many historical myths and legends. Downton Abbey's Tom Cullen plays the leader of the Templars in a dramatic tale filled with sword battles and religious conflict. If you're into any sort of conspiracy thrillers, you've probably come across at least a few stories that invoke the Templars; this time, the story is actually about them and how they became these figures of legend.
