Matt Damon revealed that the emotional scene where Mark Watney hears Commander Lewis’s voice was entirely genuine. At that moment, the other actors had already finished filming and had gone home. The voices Damon heard through his spacesuit were pre-recorded tracks played back to him from inside the suit.
As Damon started to reflect on his character’s situation — being stranded alone on Mars for two years and only hearing the voices of his colleagues via recordings — he became genuinely overwhelmed and teared up. This authentic emotional response added a powerful layer to the scene, making it even more impactful for viewers.
Director Ridley Scott was so impressed with Damon's performance that he decided to shoot only one take of this scene, which was ultimately used in The Martian. Damon's ability to tap into real feelings in such a moment showcased his acting talent and dedication, contributing significantly to the film’s emotional depth. The scene stands out as a testament to how genuine emotion can elevate a performance, especially when combined with Scott’s direction and Damon's commitment.
