10 The writer of the novel, Andy Weir, first published his book for free on his own blog for
fun. Then people asked him to put it in a downloadable form, then to put it on Amazon for
Kindle download which he did at the then minimum price of $0.99.
9 Ridley Scott claimed that Matt Damon's solo scenes were shot for five weeks straight, after
which Damon was relieved from the schedule. Consequently, Damon did not meet most of his co-
stars until the cast was reunited to promote the film.
8 In the film, when Mark learns that his communications with NASA are being broadcast all over
the world, he responds by typing something the audience does not see, yet from the reactions
of the characters, it is clearly something inappropriate or obscene. In the book, this
message is "Look, a pair of boobs! --> ( . Y . )"
7 Matt Damon admitted that the scene where Mark was getting emotional upon hearing Commander
Lewis' voice was genuine. The other actors had wrapped and gone home, and their pre-recorded
voices were actually being played to Damon from inside his spacesuit. When Damon began to
think about how he his character been all alone on Mars for two years, alongside how he was
only hearing pre-recorded voices of his co-stars who has already finished their scenes, he
began to tear up. Ridley Scott was so impressed with Damon's performance, that he only did
one take of the scene, which was used in the film.
6 The exterior Martian scenes were shot at a slower speed to simulate Mars' gravity, which is
38% of Earth's gravity. Therefore, anything on the surface of Mars needed to appear lighter
and have a slight bounce to it. However, the frame rate that was desired would not allow the
cameras to run in synch. To negate this, the film was shot at 48 frame per second during
exterior scenes, which was then sped up to the standard 24 frame per second. This meant that
much audio had to be re-recorded in post. As a result of this, synching up audio with Mark's
lips filmed at a slower frame rate would have been impossible. Ridley Scott chose to have
mark "narrate" the scenes instead of having him talk in the suit to avoid this problem.
5 NASA found water on Mars the week this movie came out in the UK.
4 Andy Weir (who wrote the novel) stated that the only moment from the book he was disappointed
to not see used in the final film was when Mark Watney makes an audio log that goes "How come
Aquaman can control whales? They're mammals! Makes no sense." after Teddy Sanders wondered
what Watney was thinking about up on Mars.
3 A rare instance where Sean Bean's character does not die, rather he just gets asked to
2 The Mars exteriors were shot in Wadi Rum, Jordan, which has a red colored desert. Another
Mars mission film, Red Planet (2000), was shot there.
1 The "cloak-and-dagger" meeting to propose the Rich Purnell Manuever is dubbed Project Elrond
after the Council of Elrond in the "Lord of the Rings" series. When this name is questioned,
the first character to explain it is Henderson, played by Sean Bean. Bean played Boromir in
The Lord of the Rings: The Fellowship of the Ring (2001) and was present during said council.
