The poster for The Martian directly features Matt Damon looking at the audience with a vulnerable expression to elicit a sense of needing help. It also uses imagery to depict the isolation and harshness of Mars compared to Earth. The bold font and sci-fi theme of the text and slogan "Help is only 140 million miles away" aim to attract middle-aged men and convey the genre and distance between Earth and Mars. Including Matt Damon and director Ridley Scott, known for sci-fi films, helps draw larger audiences familiar with their work.
