It is always pleasant to see John Mills acting but the constraints of wartime mean this is not much more than a propaganda piece plucky Brits pulling off a near impossible mission. The film quality is good but I had trouble hearing some of the dialog British accents have changed a lot in 60 years - even for a native speaker.
The underwater scenes where the crew is hunted by two German destroyers lacks the tension of later movies in particular the superlative Das Boot. I was impressed by the calculations for torpedo firing, Mills trying to get angles and his officer working out trajectories on a slide rule. Funny to think they were still using such technology on the Apollo Missions. The special effects are lacking, although the "bathtub" scenes where Mills looks through the periscope are well done as are the real submarine scenes.
The film lacks the pace and production values of later (and some earlier) war movies. It has the feeling more of docudrama.
