The characters in the film are both renamed and have their mythic alter egos swapped, with respect to the book. In the film Allie ("Ellie" in the book), rather than Will, is King Arthur (but several characters initially believe otherwise); Mr. Moore ("Mr. Morton" in the book) is in the film Mordred, replacing Marco; and Miles (instead of Moore/Morton) is Merlin. In the film, Marco reveals himself to be a member of the "Order of the Bear", and determined to protect Will (believing him to be Arthur), although Allie initially believes Marco to be Mordred.
