This has been a favorite movie of mine for many years. Its narrative relates the story of a group of eccentrics--the British Army leaders were looking for imaginative minds--to undertake a hazardous mission is small rowing boats--cockleshells--against the Nazis' ships berthed up a river. The body of this very-entertaining film comprises four parts: 1. recruiting the volunteers. 2. early training of the successful applicants. 3. later training under better discipline and 4. the raid itself and its aftermath. The underlying theme here is that even minds free of dictatorial-system thinking require self-discipline, and regulation by authorities. The films is B/W and very ruggedly filmed. The director was Jose Ferrer also, with major contributions by writers Bryan Forbes, Richard Maibaum and George Kent. Music by John Addison adds greatly to the proceedings. The serviceable cast includes Jose Ferrer as the group's enigmatic and unorthodox leader, Trevor Howard as the man who wants more discipline and is proved correct, Anthony Newley, Victor Madden, Dora Bryan, David Lodge, Peter Arne, Percy Herbert and many others. The highlight of the early part of the film is an illegal challenge exercise--the volunteers hare told to try to get back to camp from a long way off with no resources whatever. Training at managing the kayak-like craft to be used on the raid also provides some early laughs. This is an honest, well-mounted and vastly- entertaining film whose subject is really human nature and the demands made on imagination and on self-discipline in times of war. The great raid itself is staged mostly at night and is extremely well-presented visually and in its blocking. The escape following the success of the raiders' efforts against German ships that are their targets is the final achievement in this taut and very-well-made film. But the individuals, their relationships, characters and actions are what one remembers. A very-well remembered film, and one admired by many, including myself.
