- In order to become a qualified astronaut role, Matt Damon needs to go through a series of physical training every day, including strength exercises, running, skipping rope and so on.
- The crew found that the Martian spacesuit in reality is very large and heavy, and Scott doesn't like such clothes, so the final design adds more practicality and aesthetics to the original version.
- The crew produced a total of 15 spacesuits for the 6 astronauts in the film.
- Jessica Chastain learned from Hathaway that wearing a cool primer in the spacesuit during filming would not be hot.
- The screenwriter of the film, Drew Gundam, initially planned to be a director, but then he was busy directing "The Sinister Six" and retired from the directorship.
- The film was originally planned to be shot in Australia, but the local government did not agree, so this plan was not realized. Later I chose to shoot in Hungary because the locality has one of the largest and highest studios in the world.
- Many of the scientific and technological achievements set in the filmare applied in this film, especially the spacesuit.
- The crew really planted potatoes in the studio and relied entirely on their natural growth to film the scene where Matt Damon planted food on Mars to survive.
- The crew set up about 20 scenes, which is not much compared to other films, but these scenes are very exquisite in craftsmanship.
- Ridley Scott saw the script and liked it very much, and even postponed the filming process ofand quickly took over the directorship.

Melissa Lewis: All right team, stay in sight of each other. Let's make NASA proud today.
Rick Martinez: How's it looking over there, Watney?
Mark Watney: Well, you will be happy to hear that in Grid Section 14-28, the particles were predominately coarse but in 29, they're much finer and they should be ideal for chem analysis.
Rick Martinez: Oh, wow. Did everybody hear that? Mark just discovered dirt.
[laughs]
Rick Martinez: Should we alert the media?

Bruce Ng: Mars' atmosphere is so thin, by the time the ship's going fast enough for air resistance to matter, it'll be high enough that there's practically no air.
Vincent Kapoor: You want to send him into space under a tarp?
Bruce Ng: Yes... Can I go on?
Vincent Kapoor: [frustrated look] NO.
