This film's opening prologue states: "This film was completed before the tragic loss of H.M.S. Truculent, and earnest consideration has been given as to the desirability of presenting it so soon after this grievous disaster. The Producers have decided to offer the film in the spirit in which it was made as a tribute to the officers and men of H.M. Submarines, and to the Royal Navy of which they form a part." See more »

An accurate portrayal of courageous men
6 May 2009 | by (United States) – See all my reviews

I first saw this movie at the time of its original release, & it has remained in my memory quite indelibly. Particularly as one of your submissions referred to the sinking of an actual British submarine at the time of the release of "morning departure". HMS "Truculent" was the name of that submarine & the nation was very somber, but I believe the the movie realistically brought home to the public what these submariners went through. My father had served in the Royal Navy during WWII on Destoyers & had his ship sunk under him while in the Mediterranean. So I appreciated the fine acting & portrayal of the courage of the men in the Royal Navy. John Mills always epitomized the character of the rolls he took & this was one of his best for me, except for maybe Scott of the Antartic, but that's another story.
