Some people think the recent movie The Martian is a true story. See the Buzzfeed page.
Matt Damon did not go to Mars
This is like my post on how some people believe there is sound in space because of Star Wars.
Also, look at the poster above. It’s hard to tell that the title of the movie is The Martian. Obviously the marketing people thought that sounded kind of hokey, so they make the subtitle “Bring Him Home” look like the actual title.
This is like how the Tom Cruise movie Edge of Tomorrow was rebranded as “Live. Die. Repeat.” I think I saw it in a rental store under that second title, not the first one.
