I remember Zimmer saying something like he didn't even want to touch this movie score cause he didn't want to even attempt to try to follow Williams score and iconic theme.
Wonder what changed his mind. A talk with Williams, more money?... really curious about why the change of heart.
edit- heh superherohype.com mentions it...
"While Zimmer may seem like a natural fit for the project, he shot down rumors of his involvement late last year in an interview with The Hollywood Reporter.
"My heart belongs to Batman," said Zimmer of scoring the film. "I wouldn’t even know how to go and give voice to it."
Zimmer went on to explain that one of the troubles with tackling the character musically is that, in doing so, one can't help but fall in the shadow of John William's iconic score.
"[It] happens to be one of his greatest themes," Zimmer said, calling Williams "the greatest living composer". "So no. And I’m not thinking of rewriting Beethoven’s ninth either. It just sounds like a thankless task, you know? So that’s unequivocally a no."
Whatever has happened to change Zimmer's mind remains to be revealed, but check back for updates as they become available."
