Disney's John Carter is in theaters now, and before I see it I thought I'd tour you through the similarly named tie-in books. (Except for the Dynamite comics, which Mike has covered here before, and which may not survive the ERB estate lawsuit anyway.)
Stuart Moore, who also wrote "Namor" for Marvel and "Firestorm" for DC. I'm saving it until after the movie, but I generally enjoy Moore's work so I think it'll be good. The reason I bought this book early is that it's a trade paperback with a copy of Edgar Rice Burroughs' original novel "A Princess of Mars", which I wanted to read before the movie. I didn't love the ERB novel as much as my friends who read it when they were kids, but I did enjoy it enough to want to read more. I don't know if I'll get through all 10 other books, but I'll try the next two. Sometimes when you go back and read the originator of something after reading all the things that imitated it or were inspired by it, the original seems cliche. (For instance, I couldn't make it through William Gibson's "Neuromancer" because I had already read many other cyberpunk novels.) That didn't happen to me too much here. The book starts a little slow and the language is a little archaic (though not as much as you'd expect for a 100-year old novel), but by the end I was thoroughly engaged. Disney has also issued collections of the other books in the series but according to an Amazon review they don't include Burroughs' introductions, which are part of the fun. The original novels are in the public domain now, so you shouldn't have a problem finding other editions in print or online.
John Carter superfan Peter David, and drawn by Luke Ross. There's a problem writing a prequel, of course, because John Carter is firmly on Earth before the movie starts and that's not too interesting. (It's not "John Carter of Virginia", after all.) David solves this by having Carter appear in a framing sequence and narrate the story from somewhere in the future. The story, as told to Carter by Dejah Thoris and Tars Tarkas, shows Thoris and Tarkas in separate stories that intersect even though they don't know that. (Until Carter tells them after he tells us, I guess.) It's very well done and I think will get readers even more excited about the film. Luke Ross' art matches the look of the movie perfectly, and there's a nice section of some of his line art accompanied by the script to #1 in the back. (It's a regular-sized trade, so I recommend this over the individual issues because it's cheaper.)
also seems to have a reprint of these issues. I would stick to the Marvel edition, but there are reprints of DC's John Carter title and some earlier work by Jesse March at that link. I'm interested in those books too, but I want to finish this one first.
The Art of John Carter is a book of design artwork from the movie, similar to the ones issued last year for Thor and Captain America. These are usually great, but I'm saving this one to look at after I see the film.
Under the Moons of Mars (New Adventures on Barsoom) is a collection of new John Carter short stories by such authors as Chris Claremont, Joe R. Lansdale, and Jonathan Mayberry with spot illustrations by Mike Kaluta, Charles Vess and others. I'm saving it until after I've read more of the original novels because there are probably references that I'll miss otherwise. The same publisher also has a trade of the first three ERB novels, but I'm not sure if it has the Burroughs introductions because someone bought it off the shelf at The Comic Book Shop last weekend before I could take a look at it!
I hope that helped you find something you might enjoy reading, whether or not you plan to see the film, and I'll be back with a movie review soon.
