This series must of been a real challange to make. It was so realistic and kept me on edge. Even though I knew the story. The children even though I watched it in Thai, were amazing. The underwater scenes were so well filmed. I am unsure if the the actors from the US Uk and Australia were actors or real divers with SEAL training. But all were good. I watched the real story a bit after but I found it took away from the series. It was sad to read about the lead actor who passed away.as I would like to have seen him in other films. I hope that all of the kids both the real.ones and the actors have a wonderful life ahead of them.
