Trivia, insights & behind the scenes
The Sarmatian hypothesis was championed by historian C. Scott Littleton, who noticed striking parallels between Arthurian knights and Iranian cavalry traditions—including the dragon standard and sword-in-stone legends.
Fuqua originally wanted a hard-R cut with more political complexity; studio demanded PG-13 heroics. The theatrical version is essentially the compromise nobody wanted.
