Gray lady Down 1978

The photographic effects by Howard A. Anderson Company for this sunken submarine rescue movie are very competently staged and shot. IMDB states that the underwater miniatures were shot in a smoke environment, however the bubbles that are visible in many of the shots seem to me to be actually there and not composited, also  the way the collapsing sand and silt flows and billows suggests a fluid environment so it seems to me that the miniatures were more likely shot wet, in a tank.

They were Expendable 1945

Some spectacular pyrotechnic work by Arnold A. Gillespie's crew on display as a miniature Japanese cruiser is hammered by torpedoes from PT Boats in this John Ford directed movie.

The miniature cruiser was built at 1/16th scale and painted black for the day for night scenes it appears in. The explosions were all set off from steel mortars on the decks and in the water in front of the model which was not unduly damaged. An outboard motor was employed in MGM's lot 3 tank to produce the wake from the foreground PT boats P.O.V. (point of view).

 

                                    

Morning Departure 1950

AKA Operation Disaster (US title)

Only one camera angle on a portion of a submarine model is used a couple of times in this movie based on a stage play about the sinking of a submarine. The first shot of the model the camera slowly zooms in, the last it slowly zooms out.
