For the longest time -- until earlier this week, in fact -- I was convinced that Jason Reitman's next directing project was Diablo Cody's horror flick Jennifer's Body. Maybe that's because at a Team Juno roundtable interview last year, the two of them talked about it like it was their project (which it is, sort of -- Reitman's producing). Anyway, it's actually Karyn "Aeon Flux" Kusama who is directing Cody's follow-up, while Reitman is moving on to helm an adaptation of Walter Kirn's Up in the Air.

I strongly recommend the novel, which is a terrific satire about a perpetually transitory businessman obsessed with collecting a million frequent flyer miles. I liked it better than Kirn's more popular Thumbsucker which was already adapted into a film. The movie could be very funny in the hands of a guy like Reitman -- sharp and insightful. It should be closer in tone to Thank You for Smoking than to Juno.

Reitman has already shifted the project into a higher gear by setting his sights on George Clooney, who's in talks to star as the narcissistic protagonist. While I'm pretty sure the character is quite a bit younger than the actor, Clooney has precisely the effortless comic chops this project needs. His profile won't hurt, either.
