July 20 (UPI) -- Acclaimed director Ron Howard has shown off the creative process of his upcoming survival film Thirteen Lives in a new behind-the-scenes featurette.
Thirteen Lives is set to star Viggo Mortensen, Colin Farrell and Joel Edgerton. It is based on the 2018 Tham Luang rescue mission in Thailand, in which 13 members of a junior Thai soccer team became trapped within a cave by raging floodwaters, and had to be saved by cave divers.
All 13 were eventually rescued with mostly minor injuries, although two rescue workers lost their lives in the effort.
"There were so many things that should have gone wrong," Howard said of the mission, adding, "I've made a number of movies based on real events. But this was one where I wanted to be as journalistic as I could possibly be. One of the things I wanted to convey was that the Thai people saved these boys."
