It was reported by Michael Uslan (producer of Dark Knight) that he expected BATMAN 3 to be out in 2011. I guess he was wrong. Nolan is set to direct another film now, BEFORE he thinks about starting another Bat-flick.
ComingSoon.net reports that Christopher Nolan has set up his next project with Warner Bros., an original screenplay he wrote called Inception. The "Dark Knight" director hopes to shoot the sci-fi action film in the summer for a release during summer 2010.
Inception is described as "a contemporary sci-fi actioner set within the architecture of the mind."
This pushes back any potential filming on a third Batman film, but three years -- and The Prestige -- passed between Batman Begins and The Dark Knight. Nolan has also long been attached to direct a big-screen adaptation of the British TV series "The Prisoner" for producer Scott Stuber at Universal.
