Submarine Movies Real or Fictional?

Found a fictitional deptiction of the USS Dolphin actually portrayed by the USS Ronquil (SS - 396) in the Movie "Ice Station Zebra". Did you know that the Ronquil was also a diesel sub? Yup again. Kinda interesting how the story plot goes with the Dolphin in the arctic.

Bet you didn't know that the Ronquil changed names and hands in the 1970's. Yup. We gave it toSpain. They changed the name to SPS Isaac Peral (S-32) and was decommed in the 1980's.

Oh, forgot to say that the Dolphin in this picture is supposed to be a nuke.
There's a couple of actors you would probably recognize, others you'd probably not but hey, its a movie. Supposed to be a good one. Here's the link to the site where I found the info, they also have some other good movies about submarines real or fictitional.
