Aside from the novels John Carter also made it into comic books.
I've collected comics for nearly 35 yrs now and though John Carter was never one of my Favorite Marvel comics(published in the late 70's)it did give you something Different to read from the typical super hero stuff.
I went thru my collection and pulled out a stack to reread to remember what the character was all about.
Character could be fun with todays special effects but still its such an unknown to so many people wtf invest in the attempt.
To anyone interested heres a link to a few of the old comics covers.
It was the art and covers that often jumped out at you back in those days.
