Trivia: The guy who first follows Parrada and Canessa on their expedition to find Chile is nicknamed Tintin. In one of the most famous Tintin albums the cartoon hero goes to the Himalayas to find a friend who is reported dead after a plane crash in the mountains. Most likely a coincidence, but still notable.
Trivia: The survivors are called by their real names, while the people who died have been renamed for the film. The only exceptions are Lilliana Methol, and Nando's mother and sister.
