Princess of Mars (2009)

Princess of Mars (retitled and re-released in 2012 as John Carter of Mars) is a 2009 direct-to-DVD science fiction film made by American independent studio The Asylum, based on the 1912 novel A Princess of Mars by author Edgar Rice Burroughs. The film's promotional art makes mention of how the original story inspired some elements of James Cameron's Avatar but the credits or promotional material of the film do not mention Edgar Rice Burroughs. It is not to be confused with the higher-budget 2012 film John Carter, which is also an adaptation of the novel. In Europe, the film was released with the title The Martian Colony Wars.
