 FAKE: When the elves are first seen, there is an elf that is moving  (translating) left to right in front of the train with all the  others, but the elfs body is rigid and lifeless, like a toy being  slid across the floor. Possibly the computer animation for moving  the elf from left to right was correct, but the algorithm for  animating the body motion (walking, swinging arms, etc.) was  stopped.
