Corrected entry: In the scene where Iorek Byrnisson has just retrieved his armor, they are in Trollesund, Norway. Yet the soldiers are speaking Icelandic, very poorly I might add.
Corrected entry: When Lyra rescues Billy Costa, she realizes that he does not have a daemon. however, as soon as Lyra and Iorek reach the Gyptian camp, Ma Costa comes running at them and says "We'll find your daemon, Billy."
