A young man who survives a disaster at sea is hurtled into an epic journey of adventure and discovery. While cast away, he forms an unexpected connection with another survivor: a fearsome Bengal tiger.
During a manned mission to Mars, Astronaut Mark Watney 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.Written by

At various points in the movie, the "head up display" of Watneys space suit is shown, giving environmental and suit data on the atmospheric pressure and oxygen content.
There are two major problems with this:
The suit value is around 4.7 PSI and 21% oxygen. That gives a "Partial Pressure" for oxygen of only around one PSI, which is not sufficient to support life - the minimum for survival is around 2 PSI, with nearer 3 PSI to allow normal levels of exertion.
4.7 PSI is a standard for NASA, but at that pressure almost pure oxygen is used.
By comparison, the HAB pressure are shown as around 12.5 - 14 PSI with 21% oxygen, giving around 2.5 - 3 PSI oxygen, roughly "earth atmosphere" range.
This gives the second problem - dropping from 12.5 or 14 PSI to 4.7 PSI pressure requires a progressive decompression sequence each time, which takes over two hours by the NASA protocol.
The astronaut must pre-breathe pure oxygen to purge nitrogen from the body for this time, plus a period of "vigorous exercise" at the start of each pre-breathing and decompression sequence.
Without this, the astronaut will get "the bends" due to nitrogen in the body tissues forming bubbles. See more »
All right team, stay in sight of each other. Let's make NASA proud today.
How's it looking over there, Watney?
Well, you will be happy to hear that in Grid Section 14-28, the particles were predominately coarse but in 29, they're much finer and they should be ideal for chem analysis.
Oh, wow. Did everybody hear that? Mark just discovered dirt.
Should we alert the media?

Having read the book, and being very impressed, I was looking forward to the movie interpretation. I was not the least bit disappointed. I was hoping this movie would not be an overacted, overproduced and sappy version of the original, and I was pleasantly surprised that the story played out without the overblown extraneous embellishment that Hollywood seems to depend on so often.
It was great to see how the screenplay added extra material that was not in the book, and it enhanced the story to make it even better. The characters were interpreted with full respect to the intention of the author, Andy Weir, and nothing was overdone. The pacing and editing of this movie was some of the best I've seen, in fact, some of the one-liners from the book are done so quickly it pushed the story forward relentlessly.
One thing that struck me is that everyone seemed to be enjoying themselves, and I think that could be a testament to the originality and uniqueness of the book. I believe anyone who reads the book is captivated and involved with the story from beginning to end, and it's possible this comes across in all phases of the production; the acting, the sets, sound, everything. They all knew they had some great material to work with and ran with it.
