Need some help with the name of a movie seen when I was a kid.
I have no clue what the title is maybe someone could help me
The story is of a cruise ship that sank. When the ship sank many ppl still onboard survived when the ship went down. Creating sort of a underwater habitat, and survivor were waiting for rescue...Rescue never came and the survivor adapted living in the wreck... created there own oxygen, food, actually starting living on the wreck. after many years.. by luck some scuba diver found the wreck, and found out that ppl were living in there. and went to the hard task of bring them to the surface, facing a huge challenge because some ppl didn't want to leave since then spent all there life on the wreck, and were scare of what they could face on the surface

if anyone know about that movie please let me know.
I been looking for that movie for quite some time
Thanks
