From the current hit "The Martian" starring Matt Damon to the upcoming December film "Star Wars: The Force Awakens," Hollywood is producing movies about space at warp speed.
Still, for those who actually work and live in space, how accurate are these movies? CNBC's "Fast Money" turned to the authorities: International Space Station Cmdr. Scott Kelly, who set the U.S. record this month for the most time in space, and astronaut Dr. Kjell Lindgren.
"I thought 'Apollo 13' was a great movie because it portrayed the characters very well," said Kelly. "Certainly the movie 'Gravity,' although there was, you know, a lot about it that didn't really ring true on a personal level, the space station … looked very realistic." The $100 million Sandra Bullock and George Clooney vehicle became a critical darling and box office juggernaut after it debuted in 2013.
"I mean we watched that on board and it was almost kind of creepy seeing the space station that we're living in portrayed in such a vivid way," Kelly said about "Gravity's" realistic setting.
"The Martian," about an astronaut being left behind during Mars mission, was mostly accurate, according to Kelly who has spent nearly 400 days in space.
"The science part of it and, you know, the technical aspects of the mission seemed very believable and very true," said Kelly, who declined to disclose his favorite movie about the final frontier.
While those films focus on the larger issues of living in space, one area that they don't dwell on is the simple day-to-day activities, like eating and drinking.
And, according to Lindgren, Hollywood might be missing out on some out-of-this-world visuals.
"Kind of like 'Pac-Man,' " was how Lindgren described drinking in zero gravity, as a foil container with water was squeezed. The astronauts then grabbed droplets shaped like marbles with their mouths.
Kelly and Lindgren have been researching how long-term stays in space affect the human body, conducting hundreds of experiments and making spacewalks. Perhaps their mission will help provide more plot fodder for the silver screen.
