Sid Perou’s deserved reputation for film making can be summed up by this fantastic caving film from 1984.
The film follows a large international expedition exploring the Cristobal Basin of Chiapas State, Mexico. This film is epic. We are treated to massive subterranean chambers, filled with huge stalactite and stalagmite formations. Then filming becomes tightly shot and very claustrophobic, as pioneers attempt to free dive constricted, unexplored submerged passages. The cavers are continually on edge; just one bit of luck, one more push, another hair breadth risk away from discovering the biggest caves in the world!
Fighting the jungle, illness, false leads and some impressive beard growth the team finally make a breakthrough and it soon becomes clear that some of these caves are undoubtedly the most exciting ever to be explored.
