Princess of Mars (also released on DVD as John Carter of Mars[1]) is a 2009 direct-to-DVDscience fiction film made by American independent studio The Asylum, loosely based on the Edgar Rice Burroughs novel A Princess of Mars (1917). The film's promotional art mentions how the original story inspired some elements of the James Cameron film Avatar (2009), but neither the credits nor promotional material mention Edgar Rice Burroughs. It is not to be confused with the higher-budget science fantasy film John Carter (2012), which is a direct adaptation of the novel. In the UK, the film was released with the title The Martian Colony Wars,[2] and in other international markets (such as Japan) with the title Avatar of Mars.[3]
The group of Tharks, led by Tars Tarkas, takes Carter to their leader Tal Hajus, guarded by Tars Tarkas' daughter Sola. Learning that Tarkas gave Carter a military rank only Hajus can give, Tarkas and Carter are forced to duel. Upon winning, Carter faces Sarka, an Afghan mercenary who had betrayed him. When Sarka escapes, Carter helps Tarkas kill Hajus and become the new leader of the Tharks.
Captain Carter then learns that Dejah Thoris has fled to the planetary air-cleaning station that keeps Barsoom habitable, which Sarka damages, causing the atmosphere to deteriorate. John Carter and Sarka face each other in a duel, but Sarka is killed by an insect during the fight. After Carter and Dejah Thoris reactivate the station, Carter is returned to Earth, where he declines to tell his superiors about his adventures for fear they will colonize Barsoom, and returns to military duties while hoping one day to return to the planet.
