Was Matt Damon the first choice for the lead role in The Martian?
That makes sense. I'm curious, did Matt Damon do anything special to prepare for the role?
Yes, actually. He spent a lot of time talking to science experts and astronauts to try to get a better understanding of what it would really be like to be stranded on Mars. He also underwent extensive physical training to prepare for the role.
