I was pleasantly surprised by the number of women in this film, given it was a sciencey film about space.
Yes, Matt Damon is the main character, but the mission commander is a woman (and she's awesome), there's another female astronaut, and the most prominent character in the control room is a woman. All the NASA top bods and engineers are men, but there is a woman in the meetings (NASA media director). The deputy of the Chinese space agency is also female and a key decision-maker.
When they do shots of the control room there are plenty of women, and also when they show an astronaut training class, I think it's 50% female.
