This movie depicts "Operation Source" the Royal Navy's secret operation to destroy the Tirpitz. This is probably the best movie depicting midget submarines and chariots. Sir John Mills in fine form, and made in the mid 1950s, depicts gear, uniforms and setting not too far from the era. Plot line, it actually follows the basic facts of the real operation, and an earlier operation involving chariots. Some tense moments in the mini subs, and it says a lot for a film where a lot of drama can occur just in one set. Germans are all speaking German and don't come across as 2 dimensional which is always good - though no subtitles (they didn't get used in film before the 1960s). Only problem I would say is the film doesn't make it clear what the results of the mission were, but a minor point.

Reference A Boy's Own Story. It was actually Donald Sinden and not John Gregson who pushed the mine away. Otherwise a good summary as are all the others. I had not seen this film for many years and it brought back memories of an earlier time when things were so much simpler The acting was good and the Brit stiff upper lip was very evident. The actions of the Germans was as I expect they were in the German Navy. At the time of the making of this movie many Brit movies, whether comedy or drama were being made and the acting was good and there were no overt scenes of gratuitous sex and violence in those days. It would have been good in color but not much of that in those days.

"Carry on chappies, let's lerd that high explersive into the berts". Very stiff-upper-lipped John Mills et al in a very "Boys Own Annual" movie. A lot of variety, and an interesting plot, let down terribly by dreadful special effects (a view from the top of a five-foot periscope looks DOWN at the decks and mast of a battleship!!!!); and an atrocious lack of continuity. Had the characters been portrayed with even a fraction of realism, rather than looking, talking and acting like animated cutouts from war propaganda posters, the movie may have ended up with a shred of credibility. Even worse than say "Battle of River Plate".

A film about an atack on the German warship TIRPITZ a story that is well told,with tense and tragic moments.The story shows how ordinary men can perform extraordinary taskes when their country is at war.Wether the story really happened like this I do not know but once you start watching this film grips you,I would like to know what happened to the guys who are involved I hope they went on to lead fullfilling lives because they are true heroes.
