Edgar Rice Burroughs created this character in 1917 in his published book, A Princess Of Mars. This was the first of 11 novels featuring the character, and is science fiction in its early years.
Disney really goofed it up when they made the movie, "John Carter", and didn't even bother mentioning Mars in the title.
I'm really surprised this hasn't succeeded as an absolute blockbuster. From the artwork by Frank Frazetta to the dozens of comic book portrayals, it really lends itself to being an easy winner.
One thing that does intrigue me, is the manner in which the central character gets to Mars in the original book. He goes into a cave while fleeing Apache Indians, goes unconscious, and finds himself separated from his physical body - astral projecting. He then looks up at Mars and then finds himself on Mars. He has a number of adventures there, and then dies on Mars, and finds himself back in his body in the cave.
