I believe it is from the late 90s to the early to mid 00s. The movie has some explorers, astronauts I think, that find a spaceship on the ocean floor. They go on board and find out that that they are in the very near future. They find the word basura on the ship somewhere which I think they figured out was a garbage chute. I think they're stuck on the oceanfloor and running out of oxygen and need to hurry and investigate.
I didn't see the whole movie but it looked kind of cool and would like to see the whole thing. Thanks for reading and all your help.
