In 1979 the legendary French comic book artist Moebius did the conceptual art for Ridley Scott's sci-fi masterpiece Alien.
Some things of course weren't used for the film, like the illustration of an orange spacesuit above left.
In 2015, three years after Moebius' death, Ridley Scott made The Martian.
The above drawing sat in Ridley's "bottom drawer" for 36 years.
For more on Moebius - here's a 19min BBC documentary on him and his incredible legacy.
