 During the production of the "El Cid" Episode, Director Scott Billups was  chagrined to find that none of the Actors hired to portray Spanish Soldiers  knew how to shoot a bow and arrows, but his Director of Photography, Joe di  Gennaro was a trained Archer. So, he dressed his DP in Armour and  photographed him in front of a green screen, launching arrows at the  camera. The Result: Every one of the two thousand soldiers defending the  Castle Valencia was portrayed by his Cameraman!
