Continuity mistake: In the very first shot of the episode, Rey and BB-8 are walking in the sand, and she is coming up on a giant sand dune to her left before her. Other large sand dunes are also visible in the background. Yet after that first shot, none of the massive dunes are ever seen again, and when they encounter the sand worm, all the dunes around them are significantly smaller. (00:00:23)
