Zimmer's Dark Knight Rises Score

1. The Dark Knight Rises theme

Oscar-winning film composer Hans Zimmer, who scored Christopher Nolan's Batman Begins and The Dark Knight, was once again called on for scoring-duties. And, as in the first two films, has created exactly the right claustrophobic, brooding yet heroic soundtrack that Nolan's blockbuster required.

2. Batman's music composer Hans Zimmer

Zimmer once again collaborated with James Newton Howard. The pair had previously worked together on the scores for both Batman Begins and The Dark Knight.

3. Batman's fans chant

A main feature of the soundtrack is a multiple-voiced chant. Batman fans from over 107 countries lent their voices to the chant via the internet.

4. Hundreds of thousands of voices

Speaking to collider.com, Zimmer said: "The chant became a very complicated thing because I wanted hundreds of thousands of voices, and it's not so easy to get hundreds of thousands of voices. So, we Twittered and we posted on the internet, for people who wanted to be part of it."

5. Fans become part of the soundtrack

Zimmer explained that the fans were as much a part of the film as the characters and he had them in mind when he was composing. He said: "We've created this world, over these last two movies, and somehow I think the audience and the fans have been part of this world. We do keep them in mind. And I thought it would be something nice, if our audiences could actually be part of the making of the movie and be participants in this."

6. Batman's score on iPhone and iPad app

Zimmer has created a free, interactive app for iPhone and iPad called The Dark Knight Rises Z+, which allows users to sync Zimmer's score with their own lives depending on their location, activity and mood.

7. Batman begins again

The film picks up eight years after the Dark Knight left off when Christian Bale's batman was fleeing the authorities after being falsely accused of murder.
