Just in time for the release of The Dark Knight on DVD and Blu-ray, director Christopher Nolan has started talking again about the third installation in the reboot of the Batman franchise. He would like to shoot an entire film on IMAX as a kind of filmmaker's practice for the Dark Knight sequel. Oh, and about that sequel...
Nolan said that, "It was obvious when the box office was so big ($530 million domestically) that we had underestimated how ready fans were to reboot the franchise.” As for shooting the sequel completely in IMAX, this could be a problem. Aside from the prohibitively large size of the cameras used to shoot the 70mm film, the noise these cameras produce make recording dialogue impossible, requiring lots of ADR (Automated Dialogue Replacement) in post production.
A possible solution to this is to use a 65mm camera for all scenes with dialogue, and then shooting the rest of the movie on IMAX.
However he goes about shooting the next Batman film, rest assured he's hard at work on the story. He's been "jotting notes and doing some rough outlines for a third story," but wants to make sure the last film in the triology counts. Nolan stated that, “The worst thing you could do now that you’ve gotten the plane back in the air is mess up the landing."
Don't mess it up, Nolan. Many eager fans would go down with you.
