Trivia

Due to lack of work, the rescued miners took roles in the production of the movie being filmed about its history in Copiapó, Chile.

The idea for this movie was already a concern for the miners when they were trapped underground, realizing that they were celebrities on the outside. In order to ensure an equal share of the profits of any copyrights from their story, they agreed on publishing one official version of their ordeal. After they were rescued, they hired a law firm in Santiago to represent them overseas. This led to a talent agency in New York City, who chose an Hispanic American journalist and novelist, Hector Tobar, who undertook a thorough research of the events and held extensive interviews with each of the miners, their families and some of the authorities involved. The final book, Deep Down Dark, is the inspiration for the movie.

Mario Sepúlveda, one of the real 33 Chilean miners, met Antonio Banderas in Colombia during the first days of filming. Sepúlveda became supervisor of the extras for the movie.

The director of the movie Patricia Riggen demanded the actors speak English as well as speaking Spanish with a Chilean accent. This was very difficult for the actors.
