Il richiamo della foresta

Each sled dog on Buck's team (besides Spitz) was given the personality of one of the dwarfs from the Disney classic Biancaneve e i sette nani (1937): Dolly is Bashful, Pike is Grumpy, Joe is Happy, Billy is Sleepy, Dave is Dopey, Dub is Sneezy, and Sol-Leks is Doc.

The message on the telegram that Perrault receives has a uniformity and cleanness that demonstrates that this was produced not on a typewriter, but by a modern laser printer. Also, the telegram's text uses a modern Courier font not present on typewriters of that period.

Prior to re-shoots, Mercedes, Charles, and the remaining dog team die (off-screen) on the broken-up river; only Hal survives to return to Dawson and confront John Thornton in the Argonaut saloon. (Paraphrased: "I lost everything because of you: my dogs... my sister...") Despite successful test screenings, studio heads changed this to Hal saying, "My dogs ran off" -- indicating the team and (one assumes) Mercedes and Charles survived -- in an attempt to keep children from being upset.
