L'appel de la forêt

Unlike the source novel, John Thornton has a back story. They wanted Thornton's experience to be similar to Buck's for this film adaptation to show both man and dog finding their strength after overcoming tragedy.

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.

This is the first film released under the 20th Century Studios banner (previously known as 20th Century Fox).

Thus, there is a new 20th Century Studios logo, which is an updated version of the classic Fox logo.

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.
