Intended to repeat the success of the two previous films, Warner Bros. Pictures has had the great idea in mind. The studio is planning to release the next installments to "Batman Begins" and "Superman Returns" and is working on the deal with several related persons who might be tapped to work on the two big projects.
While deal with Christopher Nolan and Bryan Singer has yet reached, WB has hired Jonathan Nolan to write the screenplay for the untitled "Batman" project. The studio, moreover, has options on Christian Bale and Brandon Routh to star in. While there hasn't further confirmation on the report you better keep it here.
