- Disowned Adaptation: Le Guin's response to the film can be found here. In a nutshell, she thought the film suffered in comparison to her own novels and that is was overly violent and preachy, and that the characters are too white (which is a serious issue for Le Guin), but that the movie was merely dissatisfying rather than outright bad. Le Guin was also disappointed by the movie as a fan of Studio Ghibli, and she thought that the animation seemed rushed and less detailed when compared to their previous work. Given Le Guin's vehemently negative opinions of all prior attempts at adapting her work to other media this can be interpreted as getting off lightly.
- Reality Subtext: One could make an argument that Arren's journey's echoes Goro Miyazaki's career. A son kills his beloved father the king for Oediptic reasons and takes his sword Only to find he is incapable of using it and unable to escape the shadows, until he fully accepts his own fears and weaknesses, after which he improves.
- What Could Have Been: Hayao Miyazaki offered to adapt the book in the early '90s, but Ursula K. LeGuinn, not being familiar with his work, turned him down. By the time she watched his films and became convinced he could do justice to the book, he had retired and she had to settle for his son.
