The first official trailer for Ridley Scott’s forthcoming space rescue film: The Martian has dropped. Matt Damon plays Mark Whatney, an astronaut left behind on Mars after his team’s mission gets compromised and he’s presumed dead. Whatney cleverly puts together a message back to his team now on Earth, who have a tough decision to make — do they venture the 140 million dangerous miles back to Mars to save him? The Martian arrives in theaters November 25.
