You have to see [a sequel] as an autonomous movie, the Berlin native said. Otherwise you will end up with all the things that are the worst thing about a sequel. Before I even set off on Sherlock, and before Chris [Nolan] started shooting, I had an idea. I went to the Warner [Bros.'] music department and I said, Have I earned the right yet to book the biggest, craziest orchestra for two days, and try this experiment for Dark Knight? And if it goes wrong, if I dont like it or if Chris doesnt like it, we can just pretend these two days never happened.
Zimmer said the experiment took him to some new and distant edges of his own craft.
I had an idea of a different way of writing music, or a different way of getting an orchestra to perform music as well, Zimmer said. And basically it worked out, and snippets of it are starting to appear in the trailer. And really I have 25 minutes of very, very radical, very different stuff. There were two great parts. One was Chris came to the [recording] sessions and really embraced what I was doing and really liked what I was doing. But, in a peculiar way, the greater part was that the musicians had never worked in this way before, and really loved it. And months later, when I was doing the Sherlock sessions, the musicians were still talking about those two days, even though theyd done all this other stuff in the meantime. So I know Im onto something. Really my enemy right now is time, because I have so many ideas.
