I hadn't heard any casting news for "John Carter of Mars" lately.  The last we heard was when Willem Dafoe happened.  It was a joyous time and my worries were put to rest.  But it's been over a month since then and when you don't hear news about "John Carter of Mars", you worry because the project hasn't had the easiest time making it to production.  I ask director Andrew Stanton to call me on the cell phone I gave him for emergencies but I haven't heard from him once.  It makes me upset and disappointed not to mention that I'm pretty sure he's just using it to text his friends.

But it's a relief to hear more actors are coming on board: Samantha Morton, Dominic West, and Polly Walker.  Hit the jump to find out which roles they'll be playing.

Based off the Edgar Rice Burroughs book series, centers on a Confederate soldier (Taylor Kitsch) who finds himself mysteriously transported to Mars to find not only a war between the planet's warring people but that he can breathe despite the planet's atmosphere consisting mostly of carbon instead of oxygen (Suck it, 6th Grade Science; I have Wikipedia).

In addition to Kitsch and Dafoe, Lynn Collins is already signed on to play Dejah Thoris, Princess of the Empire of Helium and the story's love interest.  With Morton, West, and Walker, three more roles have been cast and here's the rundown of each according to THR:

Morton ("In America") plays Sola, the daughter of Dafoe's Tars Tarkas, who must hide her softer side from her warmongering race.

West ("The Wire") plays Sab Than, prince of the Zodangans who believes he is entitled to rule Mars.

Walker ("Rome") plays Sarkoja, a merciless, tyrannical Thark.

You'll either find this news exhilarating or disappointing depending on your opinion of the books of which I have none since I have never read them.  If you have read them, feel free to go nuts in our comments section.
