This was a movie where cave explorers found an underground series of moving tunnels and mazes. Most of them were killed by the sliding walls and floors of the maze. This was not The Cave but a similar movie.

Are you sure this was a movie? Are you sure you were not experiencing an amazing real real situation?

I hope this helps

Is this the same film where they find some ancient artefacts/treasure? Been looking for it myself.

And I think I've found what it is... it may be the crypt.
