Character mistake: While the engine room is flooding, Stepanik tries to put a jubilee patch on the pipe by walking towards and deflecting the water. While it looks cool for the movie, it is definitely not the correct way to apply this type of patch.
Down Periscope (1996)
1 character mistake
Directed by: David S. Ward

Continuity mistake: When they are attempting to get "between the screws" of the tanker, the underwater footage shows twin screws, but the surface footage only shows wake from 1 single mid-ship propeller.
Pascal: Jesus, Buckman! This stuff has been on the Stingray since Korea! This can expired in 1966!
Buckman: What's the matter, sir? It still tastes like cream corn.
Pascal: Except it's deviled ham.
Trivia: Tom Arnold turned down the role of Lt. Com. Dodge to play the lead in "McHale's Navy."
Question: Whose picture did Dodge salute in his cabin when he said "live to fight another day"?
Answer: Looks like Mush Morton, but that wasn't his ship. The real name of the submarine used in the movie was the Pampanito (SS-383). Her captain was Charles Jackson. It might be his picture on the wall. I can't find a picture of him.
Answer: Dodge says "We live to fight another day, Captain." suggesting that the photo is of the previous captain of the Stingray.
