I saw these movie before some 15 years ago and don't remember much of anything. I only have glimpse of it, of what I remember is as follows.
Movie is set up in submarine like vehicle, extremely huge in size. I remember A big glass dome and in that hall everything is made of whole gold.
The protagonist was a pirate or a thief.
In the climax due to some accident the ship or submarine sinks but the protagonist survives and he takes out the golden spoon which he stole earlier and throws it back in water.
Please help me identify this move. was my first scifi movie I saw it as a kid.
