re: first promotional video for "the martian"

Matt Damon is in both movies, and both movies include a setting somewhere other than Earth. Outside of that, really nothing in common.

the book is pretty fun and amusing. Damon's character has a rather hysterical personality and does some reasonably realistic ingenious engineering to stay alive on mars. its one of the things that makes this book a bit different than other movies/stories in which a marooned astronaut has to stay alive. This one actually focuses on the details of what he does to live, rather than merely assuming it just all works out - as if it is a side story.
