Did You Know?


The production of the movie was delayed for 5 months because the crew discovered that the whole line of EOS 1DC cameras Canon produced was defective and prone to bad pixel problems in 4K mode. Canon did not address the problem properly and this has led to many heated online debates and the possible initiation of a class action lawsuit against Canon by a group of EOS 1DC cinematographers.

What an amazingly gentle documentary!
17 June 2015 | by sc-51513See all my reviews

This is my first review on IMDb, but... oh what a film! I spent 20 years of my life cave diving, but this was long ago and although we did some amazing things back then, this sport has changed so much. I am very glad to see such a nicely done film, with amazing pacing, sensitivity and unbelievable content. Young people going into the sport. Bravo!! Although this movie is about cave diving, it shows so much more. It shows an attitude which is so hard to find in anything these days - a gentle approach to nature, great team spirit, great people. The beauty of caves and the spirit of cave exploration is so aptly portrayed. A must watch for sure, for anyone. Thanks to the people who made this film. It made my day!
