Christopher Nolan will be directing a new film titled Inception for Warner Bros. in the near future. The film has been described as "a contemporary sci-fi actioner set within the architecture of the mind."
What does that mean for all the Bat-Fans clamoring for a sequel to Dark Knight? Not much at this point. Remember that Nolan directed The Prestige in the three year gap between Batman Begins and The Dark Knight.
On a personal note, I hope that the fact that Nolan is working with Warner Bros. on Inception will help ensure his participation in the next Batman installment.
