I have been trying to remember this movie since I could remember. I was a kid when I saw it with my dad (early early 1990’s). I think I remember a group of people stuck in a submarine or a vessel of some sort. The part I remember is when a lady opens up a small hatch and starts crawling through it. She begins to sweat and panic and I believe halfway through her venture into the tunnel water rushes in and she ends up dying
Posiedon adventure – People stuck in a capsized ocean liner.
Original http://www.imdb.com/title/tt0069113/
Remake: http://www.imdb.com/title/tt0419358/
In my opinion the original is far better.
I saw this movie ages ago, so my memory might be playing tricks on me, but I think this scene is in “Goliath Awaits” starring Mark Harmon. I hope that helps!
