I just fell into the swamp that is watching reels, and saw an excerpt from an unnamed war movie about WW2 in the Pacific. It was a submarine full of 1950s looking guys, but it was the shots of the submarine being hammered with depth charges underwater that I liked. They were sailing through Anacharis plants, in what must have been a large freshwater aquarium for the time. Someone had put quality work into the submarine model, but the set was a touch shakier.
Or, back in the day, the aquarium hobby wasn't for the faint of heart. Depth charge the snails!
