Did You Know?


Worsley (Charles Baker) and Greenstreet (Anders Danielsen Lie) (the crew of the refuelling station) are both named after members of the crew of Ernest Shackleton's ill-fated Antarctic expedition of 1914-1917. They were the Captain and First Officer respectively, as they are in this film. See more »


In a voice-over in the trailer, Stanaforth reports; "The ship is going 160,000 miles per hour". This is 44.4 miles per second. The fastest spacecraft relative to the Earth was New Horizons, which set off to Pluto at 36,373 mph - 10.1 miles per second - considerably slower. The Juno spacecraft sent to Jupiter reached a record 165,000 mph, but this speed was relative to the Sun, not the Earth. The ExoMars craft sent to Mars left Earth at 20,500 mph. In addition, a caption states; "The journey will take 270 days" which is a reasonable time to reach Mars. However if the craft really did travel at 160,000 mph it would only take 81 days, again showing that the value of 160,000 mph is incorrect. See more »

What a gripping performance by Mark Strong
8 June 2016 | by mapikaSee all my reviews

After all these bad reviews I practically expected nothing and was positively surprised.

Indeed it's not a Thriller. There's no action in common ways, and yet it is a challenging story about one man who at all costs wants to become the first to live on Mars, brilliantly portrayed by Mark Strong and his supporting actors.

I would never compare it to "The Martian". All they have in common: the red planet and survival. If you really need a comparison, take "Gravity" or "Moon", though here was obviously much less budget available. So in this case I really don't care about technical, astrophysical goofs.

It's a psycho-philosophical Sci-Fi-Drama; small, profound, serious and quite slow. Therefore it hopefully will achieve more acknowledgment in future.
