For the first hour or so, this fictionalized biography of "Jack London" is not bad. Michael O'Shea brings some energy to the role, and in general it conveys some of the basic characteristics of its subject's life reasonably well. The last part of it was heavily tailored to the time in which it was filmed, and unfortunately it is now only of interest as an example of how badly a movie can become dated when it tries to do that.
Most of the movie is a collection of distinct experiences in London's life, tied loosely together. It works all right, and it effectively conveys the irregular nature of his lifestyle, with some courageous acts being mixed in with his involvement in disreputable and even illegal activities. The low budget nature of the production occasionally keeps some of these sequences from being more effective, but it's not bad, though it would have benefited from giving Susan Hayward and some of the other supporting cast members a little more to do.
In the last half hour or so, the story shifts its focus to a lengthy sequence that has London in Japan, reporting on the war between Japan and Russia in the early 20th century. The overt and sometimes forced condemnations of Japan make the sequence now look labored and a bit frantic, though in its time the message may have seemed to be appropriate.
There was surely a middle ground that would have allowed for brief wartime message to be inserted without getting things completely off-track. Many movies of the first half of the 1940s, in fact, do just that, and are able to hold up perfectly well today even when there are a handful of scenes or quotes that were clearly intended to have wartime significance. Jack London was a fine writer and an interesting person, but this movie ends up taking the focus too far away from him and from his life.
