The scenes with the bear howling were simulated. In reality, the bear standing up on hind legs was happily "smiling" and begging for marshmallows. The roaring sounds were dubbed in later.
The bear's name is Koda. Despite the fact that the bear in the movie is female, Koda is male. In places where the filming was too dangerous for a real bear, an actor in a bear suit was employed.
In the original script treatment, the bear was intended to die at the end of the movie.
The license plate in the movie is from Manitoba.
