I still have all the ERB books, from Tarzan to Mars, to Pellucidar, to Venus... I still read them now and then. Some are great fun, others are atrocious. Burroughs would come up with a great idea then work the same plot through his different worlds so Tanar, Tarzan and John Carter's adventures seem eerily familiar. First read Tarzan when I was 12. Wish I'd have kept that copy - it was a first edition, hardcover, from my father. All I have today are the numerous paperbacks.
Hope the film has some of the magic of the first five Mars books. After Chessmen, it got thin at times with predictable plots.
Wonder how they'll handle the nudity? IN ERB's books, Carter arrives on Barsoom naked. Dejah Thoris is naked too. Could be fun. If they clothe them, it will take away a whole part of ERB's atmosphere.
