Trivia: 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.
Trivia: The cave people are speaking Central Yupik, "Ayakataalliniukut, kituusit? Kituusit? Aruulaika!" they are basically saying "we are going to be traveling, who are you? Who are you? Stop right there!"
