One great film The 33, based on a book The 33 or Deep Down Dark by Hector Tobar. A story about miners, which are locked in a cave and survive 69 days with not a lot of food. The book can't show a lot of images, but if you want to feel everything the film is the best choice, a lot of different emotions, one moment you see anger, other rage and many others... but survive, still remaining brothers up to today!
