The Asylum released a feature-length direct-to-DVD film based on the novel, titled Princess of Mars, on December 29, 2009.
A full-length feature film of the novel had been attempted and aborted many times. Its working title was originally A Princess of Mars, but it was renamed John Carter of Mars and then simply John Carter during pre-production. It was originally due in 2006, with Jon Favreau (Zathura, Iron Man, Cowboys & Aliens) as director and Harry Knowles of Ain't It Cool News as producer. John Carter was produced by Walt Disney Pictures and directed by Andrew Stanton. Taylor Kitsch and Lynn Collins, who appeared together in the 2009 movie X-Men Origins: Wolverine, play John Carter and Dejah Thoris. Willem Dafoe, Polly Walker, and James Purefoy play Tars Tarkas, Sarkoja, and Kantos, respectively. The film's U.S. release date was March 9, 2012. [50]
