CASTLE THUNDER: During the song, The Grand Design, with Niju and the other wolves.


Mary Kay Bergman's last film.


Aleu was named for the Aleutian Islands.


The howling wolves from Balto (1995) can be seen as members of the wolf clan.


Niju, Yak, Nuk, and Sumac's characters were based on Steele, Kaltag, Nikki, and Star from Balto (1995), respectively.


The plot was inspired by some of the lyrics to "Reach for the Light" from the previous Balto movie.


Niju's voice, mannerisms, and eyepatches were based on Steele from Balto (1995).


This is the last Balto film in which Aniu appears.


Niju's character design is based on Lip-Lip from White Fang (1997) (V).


The original script was slightly longer, so some scenes were shortened.


Saba, one of Balto and Jenna's pups, was named for the island of Saba, part of Netherlands Antilles.


Has a few computer-assisted scenes.


Of Balto and Jenna's brown-and-white and red-and-white pups, three names are known for sure: Kodi, Dingo, and Saba. The two unnamed pups, the subjects of many "Balto" fan-fictions, have had names such as Kiona, Taktovik, Wolfe, Stadka, Anchorage, and Tydye.


Nava's character design is based on Balto.


The character designs (the fur patterns) of the wolf clan members (excluding Niju, Yak, Sumac, and Nuk) are based on Balto one way or another.


"Taking You Home" is played twice in the whole movie: once in the movie, and again during the end credits.


Montreal-based Canadian indie rock band We Are Wolves takes its name from Niju's line "We are wolves! We take what we need!" during "The Grand Design".


Muru's name is Latin. It could come from "mus", meaning 'mouse.' Or, more probably, it derives from "murus", which means 'wall.' This is where we get the word 'mural.' Most likely, it comes from "murus" because Muru himself turns out to be a cave painting, and he is part of a huge mural on the cave wall.
