Back in March, we reported that Megan Ellison's Annapurna Pictures would back an untitled project from director Spike Jonze and screenwriter Charlie Kaufman (the duo behind Being John Malkovich and Adaptation.).  The film would reportedly be a satire "about how world leaders gather to figure out all the seismic events that will take place in the worlds, from oil prices to wars that will be waged."  Twitch now reports that Warner Bros. has picked up the film, which means they will most likely distribute it as well.  The project is reportedly eyeing a March 2012 start date.Twitch also reports that Joaquin Phoenix is attached to star, which is a smart career move on his part.  Phoenix needs to reestablish his credibility with audiences after the I'm Still Here debacle and working with directors like Jonze and Paul Thomas Anderson is a good way to do that.
