One of my most beloved films of all times is Robinson Crusoe On Mars. It was made in 1964 before the first landings on Mars by probes. Dr. Carol Stoker of NASA Ames just pointed out that in one scene of the movie, the astronaut finds yellow rocks that burn when ignited because they have oxygen in them. The astronaut started to store the rocks for oxygen generation. Dr. Stoker said that the movie got it right!!!
