John Mills is a submarine captain, ordered with his crew to take part in maneuvers. On their way to the site, they run into a mine and are sunk. After they settle at 15 fathoms, Mills and his XO are confident their absence will be noted, and they will be located and saved. As operations proceed, however, problems arise, leaving four of them trapped.
It's based on a stage play by Kenneth Woolard, and I can see it in my mind's eye, a one-set piece. Under the reliable Roy Ward Baker, it's opened up with a prologue showing us Mills wife, and later, unsleeping Bernard Miles, leading the rescue operation. At its core, we still get to see the four characters with increasing clarity: Mills, of course, his Number One, Nigel Patrick, stoker Richard Attenborough, who starts out panicky but grows up, and stalwart Able Seaman James Hayter. As the days pass and the characters become more than sketches, the potential tragedy becomes greater.
For those of us who have seen submarine-trapped-on-the-seabed movies from several eras, it's interesting to see the evolution in rescue technology.
