We’ve got our hands on the Japanese movie poster of John Carter:
The film is largely based on A Princess of Mars, the first novel to feature John Carter. The novel was originally published as a magazine serial in 1912 and then brought out in book form in 1917. In the novel John Carter is an American Civil War veteran who is miraculously transported to Mars, known to its inhabitants as Barsoom. He learns that the planet is dying from the loss of its atmosphere and water, and that only a peaceful alliance of its intelligent inhabitants can save the species of Barsoom from extinction.
