Mars Will Come To Fear Matt Damon's Botany Powers In Latest Clip From The Martian

Matt Damon (Good Will Hunting) tries to figure out how he'll survive on Mars in the new "Let's do the Math" clip from 20th Century Fox's space-drama The Martian, directed by Ridley Scott (Prometheus, Alien).

"Right, let's do the math. Our service mission here was supposed to last 31 souls," he says in the clip. "For redundancy they sent 68 souls worth of food, that's for six people. So for just me, that's going to last 300 souls, which I figure I can stretch to 400 if I ration. So, I have to figure out a way to grow 3 years worth of food here, on a planet where nothing grows. Luckily ... I'm a botanist. Mars will come to fear...my botany powers."

Check out the clip in the video below.

During a manned mission to Mars, Astronaut Mark Watney (Matt Damon) is presumed dead after a fierce storm and left behind by his crew. But Watney has survived and finds himself stranded and alone on the hostile planet. With only meager supplies, he must draw upon his ingenuity, wit and spirit to subsist and find a way to signal to Earth that he is alive. Millions of miles away, NASA and a team of international scientists work tirelessly to bring "the Martian" home, while his crewmates concurrently plot a daring, if not impossible rescue mission. As these stories of incredible bravery unfold, the world comes together to root for Watney's safe return.

Based on a best-selling novel, and helmed by master director Ridley Scott, The Martian features a star studded cast that includes Jessica Chastain, Kristen Wiig, Kate Mara, Michael Peña, Jeff Daniels, Chiwetel Ejiofor, and Donald Glover.

The Martian will land in theaters October 2, 2015.
