Yesterday we learned that Andrew Stanton’s live-action debut John Cartner of Mars was gearing up for a November shoot in Utah, and that Tom Cruise was circling, but is no longer involved with the project. It stands to reason that in the coming weeks we’ll begin to hear casting announcements.

ComingSoon noticed that Lynn Collins, best known for playing Silverfox in X-Men Origins: Wolverine and Dawn Green on the television series True Blood, tweeted “celebrating john carter of mars!!!!!!!” One could argue that Lynn might have just finished the book, or was celebrating the news that the film is going into production, but the logical conclusion is that the actress has scored a role  in the sci-fi action adventure film.

The Hollywood Reporter has since confirmed that Collins has been cast in the project. The big shocker is that she’s not the only actor from X-Men Origins: Wolverine that has joined the project. Taylor Kitsch, who played Gambit in Wolverine and Tim Riggins in Friday Night Lights, has also joined the film. According to the report, “Kitsch will play the title character, Carter, while Collins is playing Dejah Thoris, the heir to the throne of Mars’ Helium kingdom.”

The film is expected to be the first of a possible trilogy. A Princess of Mars was first published in 1917. The movie will follow Civil War vet John Carter, who is transplanted to Mars, where he discovers a lush, wildly diverse planet whose main inhabitants are 12-foot tall green barbarians. Finding himself a prisoner of these creatures, he escapes, only to encounter Dejah Thoris, Princess of Helium, who is in desperate need of a savior.
