When much was made of the R.A.F.Squadrons flying countless missions against the enemy, and rightly so, it is refreshing that `The Sea Shall Not Have Them' shows the work done by the R.A.F. Air Sea Rescue crews. Anthony Steel plays the skipper of 2561, a M.T.B. assigned to locate and rescue a Hudson bomber that has crash landed in the north sea. On board the plane along with the rest of the crew, is a V.I.P. with vital German rocket secrets. The film then follows two strands, one showing the air crew ( including a young Dirk Bogarde) slowly freezing on the escape dingy, and the M.T.B. crew fighting bad weather, engine failure, and in one incredible scene, a new crew member sets fire to the galley. The ending although predictable ,is nevertheless gripping, and the film will rank along ,with the best of the war movies made in the 50's.
