If your biggest problem with Disney's John Carter movie is that it didn't contain nearly enough Martian wang, then James Killian Spratt's graphic (in more ways than one) adaptation of A Princess of Mars might be up your alley. Spratt is creating his own comic version of Burroughs' classic pulp, where the action is set off by giant alien knockers.
Spratt, who works primarily as a sculptor, has been adapting A Princess of Mars since 2000, and he's 21 chapters into a planned 28 chapter book. And it's unlikely that you'll see much commonality between Spratt's vision for Barsoom and Andrew Stanton's. Nudity and blood are the central features of Spratt's Mars, which he explains was always how he pictured the books:
Since I was drawing initially for my own amusement, with no thought of publishing, I pulled all the normal stops and drew the way I imagined the classic story to be written. The characters are highly underclad, yet oblivious to it; it's their normal way, and they don't see much naughty or titillating about it. The men are men and the women are women and blood is red and scary. I set out to be honest with the nudity and violence, and the devil take Pollyanna, she needs to grow up anyway.
In Spratt's mind, "honest" means an odd combination of R. Crumb and Frank Frazetta, with sketchily rendered characters. It appears that a Barsoomian man's rank is determined by the comically large size of his nethers, and that the female warriors have been specially trained to navigate around their own absurdly voluminous breasts. But I guess one person's distracting genitalia is another person's honesty.
