just a hint for casual viewer and ignore mr. crook synopsis of the battle and it could not be more incorrect . bismarck be a full battleship and not commission until 1941. gneisenau and scharnhost be battle cruiser and much large than the only actual pocket battleship he mention and the graf spee ( there be 2 other pocket battleship in the german fleet ) . the film itself be very much in the tradition of british war film and little hollywood glitz but much more accurate than hollywood history film . very much in the vein of sink the bismarck and well worth watch . graf spee be the most effective of the german surface raider but it once again prove that the submarine be a much more cost effective way to destroy shipping .
