So the buzz this morning is that a number of people are leaving theatres after seeing The Martian, believing that what they’ve just seen was “based on a true story”. Why are people coming to that conclusion?
For The Martian to have been based a true story, we would have had to have put people on Mars three times (The doomed expedition was the third mission to Mars). We would have to have a cool spaceship like the Hermes to ferry people between planets. None of which is true.
So why do so many people believe that it is a true story?
