On June 8, 2012, we'll get to see John Carter of Mars! The movie stars Taylor Kitsch, Lynn Collins, Dominic West, Mark Strong, Willem Dafoe, Thomas Hayden Church, Ciaran Hinds, Polly Walker, Samantha Morton and James Purefoy. Below is the official synopsis of the movie.
"Carter is an American Civil War veteran who goes to sleep in a cave after being chased by Apache Indians and wakes up on Mars, here called Barsoom. Formerly an Earthlike world, it became less hospitable to life due to its advanced age: as the oceans evaporated, and the atmosphere thinned, the planet devolved into partial barbarism with the inhabitants hardened and warlike, fighting one another to survive. Barsoomians distribute scarce water supplies via a worldwide system of canals, controlled by quarreling city-states. The Martian atmosphere is maintained by a power plant. Carter rescues a humanoid Red Martian princess, Dejah Thoris, from the belligerent four-armed Green Martians, whose respect he gains for his superior strength and fighting ability. He enlists the Green Martians’ assistance in winning a civil war, and saves Mars from destruction when its atmosphere plant malfunctions."
Filming on the movie, which is based on the books by Edgar Rice Burroughs, has been under-way since the beginning of the year and is directed by Andrew Stanton. It's release date means that it will come out somehwere Men In Black III and Star Trek 2.
