We've wondered about it before, and now it's been confirmed by the one person who should know: Pixar is indeed working on a movie version of John Carter of Mars, with a script written by Wall-E's director Andrew Stanton, who also worked on Finding Nemo. The confirmation came from Stanton himself, talking to fans after a convention appearance in Toronto last week.
The disclosure came at the end of the short, but extremely enjoyable, discussion (excerpts of which will be published here soon), when a writer from Suite101.com asked about Stanton's next project, to which Stanton mentioned (not too loudly) 'John Carter of Mars'.
Doubting what I'm hearing, I interject, "What is that?" "John Carter of Mars", Stanton replies. "You're confirming John Carter? Are you serious?" At this point, I turn my tape recorder back on, "...say that on tape!", I tell him. Stanton: "I am writing John Carter of Mars right now." "Oh man, you just doubled my page views!", I say. Everybody laughs.
Earlier reports have had Pixar working on a trilogy of live-action movies based around the Edgar Rice Burroughs novels about civil war vet Carter who ends up a super-strong hero on Mars after a series of unlikely and scientifically improbably events, with the first being released somewhere around 2012. If nothing else, there's no way this could be as unnecessary as the confirmed Pixar release for 2010, Toy Story 3.
