Stars of 'The Martian,' retired astronaut, NASA consultant land at 6abc

This Friday, 'The Martian' starring Matt Damon and Jessica Chastain hits theaters.

Some of the stars of the film along with a NASA expert and a retired astronaut visited 6abc studios Wednesday to tell us how they worked on creating a true snapshot of life in space; it's where math and science meet the magic of the silver screen.

A mission, a storm, and a NASA astronaut thought to have to been killed is alive on Mars and trying to stay that way.

'The Martian' is based on a book which the Wall Street Journal dubbed 'Apollo 13 meets Castaway.'

"There isn't a Wilson, though," star Sebestian Stan who plays Chris Beck said.

To bring the Andy Weir novel to the big screen, director Ridley Scott called NASA looking for Dr. Jim Green, aka 'Dr. Mars.'

"And I said 'the Ridley Scott?' Because I just loved his movies. I realized he really wanted to make this look beautiful. He really wanted Mars to pop because that's what it is, it's a fabulous planet," Green sadi.

"The film's really great advertising for NASA and how exciting and cool the space agency is, sort of reinvigorating this love of science and math and these great explorers in the world," MacKenzie Davis who plays Mindy Park said.

To make it as real as possible, Stan tells us they visited NASA and went through weightless training.

"It's a little bit like underwater, but you can't act like you are underwater," Stan said.

This movie has gotten the blessing from the people at the top and can vouch for its math and accuracy, people like Nicole Stott who spent nearly 30 years as a NASA astronaut.

"Very realistic use of tech and problem solving skills that we have and what would need to happen to get someone off the planet," Stott said.

With the news this week that liquid water was found on Mars, this script may not be too far off!

"Now we know there are resources on Mars he can use," Green said.
