Here’s something you don’t see every day… a horror flick set in 1943.
The museum ship USS Silversides (SS-236) was used for external shots of the fictitious USS Tiger Fish and Lake Michigan doubled as the Atlantic Ocean. I suppose you have to make do with what you have available. The interiors are *ridiculously* spacious with oodles of headroom and plenty of room to swing a dozen cats. Hurray for Hollywood!
