Trivia: At the very end of the film when Gregory Peck and David Niven are standing on the deck of the warship watching the explosions, you can see a very distinctive injury on Niven's upper lip. During the filming of the sequence where the commandos climb the cliffs he was slammed into the rock face by the water dumped on them to simulate the waves breaking over them. The resulting infection put him in hospital. He complains about the indifference of the film's producers in his book "The Moon's A Balloon."
Trivia: Anthony Quinn was so taken with Rhodes, the location for the movie, that he decided to buy some land there. Particularly a bay formerly known as Vagies Bay, which is still called Anthony Quinn Bay.
Suggested correction: The guns are firing across a strait. A strait is a "narrow passage." Since the targets must appear at a limited range, the guns only need a limited elevation angle.

Watch the film again. The guns are facing the open sea. There is no land visible anywhere behind the ships. If that's a strait, it's a very, very wide one.
The mission given says the guns are guarding a strait. The last shot of the six destroyers shows land behind them on the opposite side of the strait.

Other summaries explain that the strait is only deep enough for the ships at the place which matches the guns' range. So ships could not take advantage of further away or closer in.
Then what are the dark shapes rising out of the sea on the far side of the ships. If they are not islands, what are they?

Suggested correction: That the gun carriages are supposedly set on rails is not correct. In the novel template, as well as in the film, it is shown that the guns were installed on turntables. And as for their variable angles of fire - it could be due to (fictional) modifications.
