In a scene in a cave that is the lair of the "eaters of the dead," the camera takes an overhead wide angle shot of the "eaters" walking down into the cave. It is possible to see a young man wearing a burgundy t-shirt and beige shorts (a crew member), sitting against the wall of the cave cross-legged.
The story of this film is basically a retelling of the story of Beowulf and Grendel. Buliwyf is Beowulf, the Wendol are Grendel, King Hrothgar is of course himself. Ahmed Ibn Fahalan was added to lend the story historical credence as Ahmen Ibn Fahalan really did travel north from Baghdad and encountered Viking men.
