This was the first movie to be released under the "Walt Disney Pictures" logo.
The US Copyright Notice field with the Library of Congress lists Curtis Hanson as co-writer.
Although all the wolves used in the movie were tamed, at times the cameraman had to hold a chicken above their head to draw their attention to him. When needed, he gave the poultry a good jolt, which had the effect of having the chicken violently shaking it wings and getting the wolves to stare in perplexity at this behavior.
Nearly a third of the movie's budget went into filming the scene of Farley running with the caribou. Several helicopters flew overhead, herding the caribou, before the wolves were released. The filming took twenty hours a day for a month.
