Christopher Nolan will finish working on the 'Batman' series following his directing of 'The Dark Knight Rises'.
He told Entertainment Weekly: "I feel very glad that I'm doing another 'Batman' film. I think it would have been daunting to sit down and write an original script after 'Inception'. I love working within the realm and rules of our 'Batman' world. It's kind of nice to have someplace to go that I'm super-excited about.
"I must say that I'm glad - I'm very, very glad - to be embarking on the last chapter of our 'Batman' saga without any sense of obligation or duty to the studio.
"They did very well with 'Inception'. So I'm able to go into finishing our story in a very enthusiastic way."
The 40-year-old filmmaker has previously revealed the movie will not feature the classic Batman enemy Riddler as some people had expected.
He said: "It won't be the Riddler. We'll use many of the same characters as we have all along, and we'll be introducing some new ones."
