I've been researching this some:

There seems to be no actual statements that Carter is, in fact, immortal. However there is a lot of evidence that many people point out, including this passage:

"I am a very old man; how old I do not know. Possibly I am a hundred, possibly more; but I cannot tell because I have never aged as other men, nor do I remember any childhood. So far as I can recollect I have always been a man, a man of about thirty. I appear today as I did forty years and more ago, and yet I feel that I cannot go on living forever; that some day I shall die the real death from which there is no resurrection. I do not know why I should fear death, I who have died twice and am still alive; but yet I have the same horror of it as you who have never died, and it is because of this terror of death, I believe, that I am so convinced of my mortality."

This might suggest that he is immortal. But it could also be any of a number of other things. So it will have to be left up to the reader to decide. Which is probably exactly what Burroughs wanted. :)

John Carter is never described by Burroughs as actually being immortal, which would imply that, in addition to being forever young, he would also be unable to be killed. He even states at one point that he is as susceptible to mortal wounds or violent death as any other man. Extended life spans seem to be a favorite theme of Edgar Rice Burroughs, and not only John Carter, but also Tarzan, Carson Napier of the Venus series, and both David Innes and Abner Perry of the Pelucidar series, all share that same gift. Also, the entire population of Barsoom has a potential life span of over a thousand years (and a single Mars year is almost twice as long as an earth year) with little or no signs of aging once physical maturity is attained, until the final few years of their extended life span. Even beyond that, Ras Thavis, in The Mastermind of Mars has developed a process for brain transplantation, allowing a person to change bodies whenever their current one becomes, for any reason, unusable, even to the point of being brought back from the dead if the process is performed within a reasonable amount of time.

Neither John Carter's nor the Barsoomian's extended life spans are ever mentioned in the movie, probably to avoid charges that the idea was ripped off from Gregory Widen's Highlander series, though. In fact, exactly the opposite is the truth.

The idea of John Carter becoming weaker and weaker on Mars should apply to another, more well known fictional hero, who, as opposed to progressively becoming weaker as time passes, has actually become stronger.

Superman.

It goes without saying that science is seldom allowed to get in the way of a good yarn.

No implication that J C and Superman were the same type of heroes, just saying that both are fictional heroes, created in a time when adverse effects of low gravity on the human body were unknown, so it wasn't then a factor to be considered. Many fictional heroes, if scientific and/or historic fact, to name just two factors, were strictly adhered to, would never exist, making literature a much more boring media.

folks, I'm new here, but not to the subject of Edgar Rice Burroughs and his characters, If I might offer my opinions...

The term "Immortal" is not interchangeable with the term "invulnerable." Yes, John Carter is immortal (Burroughs at one point refers to him as "the unaging Virginian) He cannot grow old, or, at least, he doesn't age as normal humans do. He can, however, be killed just like any other human. As Burroughs wrote him, however, as the greatest swordsman who ever lived, living in a society where single combat with swords is the highly preferred weapon of choice, him being killed is a highly unlikely event.

Carter's extended lifespan works out quite well on Mars, where the inhabitants live for as much as a thousand years, with those lucky enough to survive that long in Mars' warlike civilization show almost no signs of aging until the very last few years. If he were a normal mortal, he would grow old and die long before his beloved Dejah Thoris showed even the slightest signs of aging.

Incidentally, I might add that, by one method or another, all of Burroughs' series focus on a character who is unaging. Besides Carter, there is Carson Napier on Venus, who doesn't age because of an elixir given to him by the Venusians, Tarzan, who was granted immortality as a reward for saving a witch doctor, and David Innes, who explains his lack of aging by saying that, since time does not seem to exist in Pelucidar, his body simply doesn't realize that it should be growing older, therefore it remains young.

Time doesn't progress either faster or slower on Mars than it does on Earth, the discrepancy lies in the difference between Burroughs' original story and the movie version of that story. Carter stayed on Barsoom for ten years before returning to Earth, not the few weeks that seemed to pass in the movie. This is a glaring foul up when you consider the state of Carter's body when he returns. For that matter, why does he return to Earth once more bearded and wearing the clothes that were taken from him his first night among the Tharks, and covered bu a layer of dust?

The screenwriters simply fouled up in changing certain elements of the original story but leaving other elements that either were no longer consistent with the new story, or contradicted it completely.

On Earth, he is ageless, until he is killed. The one time we know that he is killed, in the cave, his astral body transports to Mars and his physical body remains in the cave.

When he later dies in the Atmosphere Plant on Mars, his soul (?) is returned to his earthly body, and he lives again on Earth.

It appears that he cannot die, one way or another.

None of this makes any sense--especially an astral soul traveling to Mars and yet having a physical body upon arrival--but these are typical contrivances of fantasy fiction evolving into science fiction in the early 20th century.

Remember that Carter says he does not know how old he is. He does not say that he doesn't remember his immortal past. He's simply not sharing it with us--perhaps because Burroughs himself didn't know who Carter was.

I think he is definitely meta-human (super-human), at least because it is impossible for any human to be so strong on Mars. I mean, it is impossible to be as strong as him for a longer period of time. He would probably become weaker and weaker (bone loss and so on, astronauts deal similar stuff) even with regular exercise and also the whole idea of transporting life essence from a dying body and reforming it on Mars is quite interesting. So we truly do not know what happened to him. Perhaps some higher entity brought him back from death and made him immortal and then sent him to Mars for some higher purpose?
