This ambitious filmed biography of writer-adventurer Jack London is somewhat compromised by its too-tight budget. Michael O'Shea is well cast as London, whose rugged adventures range from the high seas to the Klondike. London's insatiable wanderlust causes friction in his marriage to the lovely Charmian (Susan Hayward), but she stands nobly by his side in good times and bad (it should be noted that the script is based on Mrs. London's memoirs). In the interests of topicality, the film contrives to have London endeavor to warn America of Japanese military expansion some four decades before Pearl Harbor. It is this story element that makes Jack London a bit difficult to watch today, despite the strong performances of O'Shea, Hayward and a superb supporting cast. ~ Hal Erickson, Rovi
O'Shea is charismatic as London and Richard Loo is stereotypically scary as the Japanese ambassador. It's basically a low-budget anti-Japanese propaganda film in the middle of WWII, but the tidbits on London's early career are clever B-movie scenes, and it's a real stitch to hear O'Shea and other low-life characters quoting poetry.
