John Sturges directs, with customary deliberateness; at times the movie seems to be suffering from iron-poor blood. Much of the dialogue is pretty sharp, especially in the submarine half, enough to keep you engrossed if you're in the mood for this kind of thing. When the action shifts to the ice, the studio-bound sets inevitably take their toll. It's not hard to see how this large, old-fashioned project misfired in the era of Bonnie and Clyde and The Graduate, but the more tantalizing question is: Why did this movie become an obsessive favorite of Howard Hughes? Maybe he liked how clean it all looks. --Robert Horton
