Filming was set to begin in 2005, with Rodriguez planning to use the all-digital stages he was using for his production of "Sin City", a film based on the graphic novel series by Frank Miller. Rodriguez planned to hire Frank Frazetta, the popular Burroughs and fantasy illustrator, as a designer on the film. Rodriguez had previously stirred-up film industry controversy owing to his decision to credit "Sin City"s artist/creator Miller as co-director on the film adaptation; as a result, Rodriguez decided to resign from the Directors Guild of America. In 2004, unable to employ a non-DGA filmmaker, Paramount assigned Kerry Conran to direct and Ehren Kruger to rewrite the John Carter script. The Australian Outback was scouted as a shooting location. Conran left the film for unknown reasons and was replaced in October 2005 by Jon Favreau.
