Based on the hugely popular sci-fi novel, The Martian sees astronaut/botanist Mark Watney (Damon) get stranded alone on Mars. The trailer was released a couple of months ago, but the movie is also being promoted using viral videos following Watney and his fellow crew members from the Ares mission. The first was a vlog-style tour introducing each person on the spacecraft, and Fox just uploaded a new video showing interviews with each of the main crew members.
As part of their preparation for the journey to Mars, each of the Ares astronauts had to spend 10 days in isolation. These interviews show each of them dealt with spending that much time alone.
Honestly, this scene is already funny enough to belong in the movie.
