With production scheduled to begin early next year, ‘John Carter of Mars’ appears to be getting all of its ducks in a row.  Samantha Morton, Polly Walker and Dominic West have joined the cast, according to THR.

‘John Carter’ centers on a Civil War veteran that dies and is mysteriously taken to Mars.  There, he takes a prominent role in a battle of Humanoids and Aliens.  The film is being adapted from the Edgar Rice Burroughs books, with Taylor Kitsch (Friday Night Lights, X-Men Origins: Wolverine) in the title role.

Morton will play Sola, the Tars Tarkas (played by Willem Dafoe).  Walker plays Sarkoja, an evil Thark, and West will play Sab Than, a prince that wants to rule Mars.

Over the weekend, word broke that Taylor Kitsch (X-Men: Wolverine, Friday Night Lights) landed the coveted title role in ‘John Carter of Mars.’  Now it looks like ‘Spider-Man 3′ actor Thomas Haden Church could end up in the film as well.

In an interview with Reel Talk, Haden Church said:

I’m probably going to do a huge science fiction drama at Disney called John Carter of Mars in the spring and that’s a very dramatic role

The actor didn’t specify which character he would play.

‘John Carter of Mars’ centers on a former Civil War veteran that dies and is mysteriously taken to Mars.  On Mars, he takes a prominent role in a battle of Humanoids and Aliens.  The film is scheduled to begin production early 2010.
