Thai officials have been generous with their praise of foreign volunteers who were essential in the complicated search and rescue operation, including the two British divers who were the first to discover where the members of the Wild Boar soccer club were sheltering.
After days of mounting speculation, a former Thai Navy SEAL diver broke the silence, revealing the boys were sleeping or partially-conscious as they were passed from diver-to-diver through the cave.
The pair also thanked all those who offered messages of support during the rescue which brought the last of the 12 boys and their coach to safety on Tuesday.
The coach, Ekkapol Chantawong, or Ek as he is known, has come under scrutiny as the only adult in the group of 13 who got trapped in the cave in the northern province of Chiang Rai on June 23 during an expedition.
The video released by the Chiang Rai Prachanukroh Hospital, located in Thailand's Chiang Rai province, shows the boys lying and sitting in an isolation ward while wearing face masks and hospital gowns. Some well-wishers at the air base prepared red roses. "They have to help each other".
Anderson said: "We were extremely fortunate that the outcome was the way it was".
That gutsy determination was on display today in a video taken from the hospital isolation ward.
He said, "Don't need to worry about their physical health and even more so for their mental health".
Hospital Director Chaiwetch Thanapaisal said at a news conference that "everyone is strong in mind and heart", The Washington Post reported. Three boys from the last group saved have ear infections. "The coach was the one to choose", he said.
Desperate attempts to free the trapped "Wild Boars" soccer team and their coach from a flooded Thai cave were hindered by wild weather and low oxygen. When divers reached them later, they brought additional food, water and blankets.
Dr Harris had been asked for by name because of his 30 years experience as a cave diver and also his expertise as a medical retrieval specialist with South Australia's MedSTAR service.
Concerns are already being raised on social media that the movie could be "white-washed", focusing more on the worldwide characters while downplaying the role of Thais.
"We just needed them to know how to breathe and not panic in the water", he said.
He added that everyone worked together without concerns about race or religion, as the goal was to save the young football team.
Pure Flix co-founder Michael Scott, who lives in Thailand part of the year, said producers from his company were on the ground interviewing rescue workers for a potential film. Two divers were helping each one make his way through very small passages filled with water. They were all were rushed to the hospital mostly because of fear of infection.
Police officers took photographs of each other at the massive cave entrance, as pumps continued to suck out huge volumes of water.
