Sends a shockwave through all other submarine film

Thinking this is yet another submarine film? This is THE submarine film. The mould that others trying to follow.

Watched in the original German, with subtitles, or with the dubbed English does not detract form what is a subliminal piece of work.

Tension, humour and action combine to give a film irresistible grip until the last.

Splash you face with water and sink yourself into the depths of film I still marvel at with every watching.
