OVER the last 20 years, Matt Damon has arguably the highest batting average of any actor of his generation. The critical and commercial hits, from Good Will Hunting to The Talented Mr. Ripley, from the Oceans franchise to the Bourne movies, from Syriana to The Departed, far outnumber the less-remembered (but still solid) works.

Hey, even We Bought a Zoo ended up grossing over $120 million worldwide, and I still say it鈥檚 not THAT corny.

In Ridley Scott鈥檚 The Martian, Damon plays Mark Watney: botanist, astronaut, University of Chicago grad, Cubs fans, deep-dish pizza lover and all-around good guy who鈥檚 part of a crew on an expedition to Mars. Once they reach the Red Planet, they go about their daily business of collecting samples and monitoring the atmosphere and compiling data 鈥 until a massive storm hits, and by the time the dust clears, Mark is alone on Mars.

In a telephone interview, Damon talked about the challenges of filming a movie epic in scope and yet in some ways deeply personal, whether he would ever go to Mars 鈥 and what a certain political candidate would say about an astronaut who was left behind on the Red Planet.

鈥淭he script came (to me) before Ridley was even attached,鈥 says Damon.

鈥淒rew Goddard, who wrote it, was attached to direct. But then he got offered a big comic-book movie he鈥檇 been dying to do for years (Spider-Man vs. Sinister Six). So he left the project and I thought it would just get postponed. But then I heard Ridley was interested, so I jumped in my car and raced over to his office and, five minutes later, we had agreed to do the movie together.鈥

Scott, of course, is the director of Alien, Blade Runner, Black Hawk Down, Thelma & Louise, et al. Recent films such as Exodus: Gods and Kings and The Counselor have landed with a thud with most fans and critics 鈥 but I think they鈥檙e kinda great, albeit in a slightly loony fashion.

鈥淚鈥檓 like you, I love Ridley鈥檚 work,鈥 says Damon. 鈥淚鈥檝e been a fan since Alien. As a young guy, Alien and Blade Runner were formative movies for me 鈥 movies that made me want to make movies. So (making a film with Scott) was at the top of my bucket list.鈥

In the opening scenes of The Martian, Mark is bantering with the crew and it looks like a prototypical ensemble space movie 鈥 until the storm hits.

鈥淚t鈥檚 about a mission to Mars in the very near future that goes horribly wrong,鈥 says Damon. 鈥淭here鈥檚 a storm and one of the astronauts, the one I play, is struck by a piece of the communications tower, and his teammates think he鈥檚 dead, so they perform this emergency evacuation and they leave Mars. The presumption is he鈥檚 not alive 鈥 but they subsequently find out he is alive and he鈥檚 on the Red Planet. So it鈥檚 about this one guy trying to survive on an inhospitable planet.鈥

For most of the film, Damon is acting alone, on location in Jordan or on a soundstage, playing a man who will spend the rest of his days or at least a couple of years (the time it would take to send a rescue team) by himself.

鈥淚t was a little nerve-wracking going in, a little odd not to have a scene partner, not to have someone to bounce things off of. But it was really fun. Ridley was never more than a few feet away. And all those monologues are pretty much from the book and they鈥檙e really entertaining and funny鈥

鈥淭he surface suit I wear on 鈥楳ars,鈥 when I put that on in Jordan, it got toasty pretty quick. Luckily, Ridley doesn鈥檛 do too many takes.鈥

Even though Mark is alone for most of the story and he has moments where he breaks down, he鈥檚 never on the verge of losing touch with reality, a la Tom Hanks in Castaway.

鈥淯nlike in Castaway or Robinson Crusoe, he鈥檚 alone, but he鈥檚 behaving with the expectation he鈥檚 being watched,鈥 says Damon, 鈥渂ecause cameras are on him all the time, and he鈥檚 leaving a log or a journal for other scientists. It鈥檚 a weird thing because it鈥檚 like, he鈥檚 self-aware because people are probably going to watch this video of him someday鈥 He鈥檚 behaving with the expectation they will someday.鈥

The Martian is really three movies: Mark鈥檚 ingenious efforts to live on a planet not designed for human life; the rest of his crew on a ship bound for home, deciding whether they should in effect turn around and go back for Mark, which will take months and months and will endanger their own lives; and the international effort on Earth to figure out a way to bring Mark home. Nations and cultures unite to save one man.

鈥淚t鈥檚 a very uplifting movie, a nice thing to put out into the world right now,鈥 says Damon. 鈥淎s another presidential campaign ramps up and everyone works to divide us all, this is hopefully an antidote to that.鈥

Imagine what Donald Trump would say about an astronaut who needs so much help.

鈥淩ight,鈥 says Damon with a chuckle. 鈥溾業t鈥檚 not my fault. He shouldn鈥檛 have been left behind. I like the guys who don鈥檛 get left behind.鈥欌

The 44-year-old Damon has four daughters with wife Luciana. Asked if he鈥檇 jump at the chance to actually go to Mars, he laughed.

鈥淚 don鈥檛 think I can bring that one up at the dinner table. Yeah, that鈥檇 be a non-starter.鈥 鈥 Universal UClick
