In the film John is inexperienced, whiny, very complaining, and is in his twenties. In the book, he is originally supposed to be experienced, knowledgeable, strong, and in his forties which he is not in the movie. The movie never takes time to introduce the dogs, their is no fight between Buck and the wild wolf pack, there is no mountain sled team that joined Buck's team in catching the rabbit, No dreams or visions seen on the fire, No fight in the bar between John Thornton and Black Burton.

Buck's fight with the moose was never included and the ending was very quick. An immense diversion though, is the perspective the movie was told in, which in this case was John Thornton instead of Buck. Because the perspective in the movie was told through John
