Christopher Nolan has spoken about The Dark Knight Rises, saying that the opening sequence for the final Batman film is "breathtaking."
The director said the six-minute opening, which will air before IMAX screenings of Mission: Impossible - Ghost Protocol, was made in order to allow him to "take time" setting up the film's story.
He told Entertainment Weekly: "My feeling, particularly on an action film, is you want to be thrown into a situation that somehow takes your breath away early in the film. I think rhythmically - you know, I view these films as pieces of music - if you start with a bit of a bang, it buys you more time to then calmly move into the story and the characters.
"We have a lot of characters in this film, a lot of people to introduce, a lot of catching up to do with the audience. So I think it was important to really throw something big on screen and then take our time."
With the film now in post-production, Nolan added: "I am excited about it. I'm only nervous about it in that the rest of the film isn't finished yet, so we're still in the evolving creative process. I wouldn't want the reactions to skew that. We try to work in a vacuum a little bit.
"It's always different in the editing room. There's a lot of discovery and a long process of re-discovery."
The Dark Knight Rises is released on July 20, 2012.
