Sci-fi adventure based on the novel 'A Princess of Mars' by Edgar Rice Burroughs which follows American Civil War veteran John Carter (Taylor Kitsch) who finds himself on Mars. John wakes up on the barren planet, known to its occupants as Barsoom, and soon learns it is on the brink of war. He makes friends with Green Martian Tars Tarkas (Willem Dafoe) and falls for humanoid princess Dejah Thoris (Lynn Collins), a Red Martian he saves from a hostile Tharks tribe. With his strength and fighting skills enhanced because of the lower level of gravity, he leads the Martians in a war against their long-time enemy, the Zodanga state, and attempts to save them from extinction when their air supply shuts down. Dominic West, Mark Strong, Bryan Cranston and Ciarán Hinds co-star.
