I must say, a film buff, and as a guy who reads and pursues history for pleasure, Navy films almost always disappointed me.
As far as the actual Naval aspect of it, I must confess that most of, I think, the populace’s understanding of Naval strategy and protocol and behavior really came from the Starship Enterprise and Captain James T. Kirk.
Clark Gable and a myriad of the great legends of Hollywood that were put back in uniform (to) relive their days.
