Mark Hamill was cast as Talus, an old Templar veteran of the Crusades who lived through a decade of captivity in the Middle East, and now tasked with training younger knights.

According to Barrandov CEO Petr Tichý, the studio was chosen partially based on the quality of the 15th-century interior they had previously built for Borgia.

[50] According to Tom Cullen, the main cast had a two-and-a-half week "boot camp" with French stuntman and fight choreographer Cédric Proust.

He says the quest for the Holy Grail would have been recognised as myth by people in the Middle Ages, and is part of the legend which has since developed around the Templars.
