As you may know a movie version of Edgar Rice Burroughs' A Princess of Mars is on the making. Roberto Rodriguez was to direct but he had to quit over Director's Guild rules conflicting with Sin City. A shame. Harry Knowles of Ain't It Cool is apparently producing so that's- hopefully- a plus point. No word yet on a cast but if you check out this fan site you'll be able to have a look-see at who is popular with the fans that have found this site. At a big ERB fan, Hugh Jackman would not be my first pick. Matthew McConaghey might be good (go watch Reign of Fire if you don't believe me)- after all, John Carter is a southern gentleman and officer.
Anyway, here's a picture of the Princess of Mars in question- the beautiful Dejah Thoris- as imagined by Adam Hughes. Who would you pick to cast as her?
BTW, if you haven't read the book you can download it free and legal from here.
