Unless you're blind or have just been ignoring me (understandably), you'll have seen me wanging on about doing a Q&A with five-time James Bond film score composer David Arnold at London's Prince Charles cinema last week. The evening came and went without any major disasters (although I wore a waistcoat in an attempt to smarten myself up and promptly spilled olive oil down it just before the interview, and that shit does not budge) and Mr Arnold was in fine fettle, spilling a small amount of beans regarding his work on Casino Royale - a screening of which followed the Q&A - and other films. If you weren't among the many millions of people who crowded into the 285-seat auditorium that evening, I've handily reproduced most of what Mr Arnold had to say below; I had to edit out all the bits where he went on at length about how much he loves The Incredible Suit because it got embarrassing.

Your score for Casino Royale is a lot more organic and less electronic than previous Bond scores That's correct. Download serial number syswin 34. So how did that decision come about? Was that you, or the producers or the director?

Most importantly, I forged a scholarly bond with my mother. Wang, Associate Professor of Information Sciences. And offered solace every time a piece of research got exceedingly tough. Gert Due Billing was a pioneer in the field of classical-quantum calculations of molecules adsorbed to surfaces.

I think with Die Another Day, someone said that some of the music was a bit over the top, and I was thinking, 'would that be for the scene where the guy who was a DNA-changed villain who became Korean – no, he became western, he was Korean – tried to kill James Bond with a space laser operated by a remote controlled arm-device while they were escaping from a melting ice palace?' That film had levels of extremity of all sorts of things in it, and the music has to react to what we're seeing. Really can't see why people found this silly When I read the Casino Royale script we hadn't cast Daniel, so it was really interesting reading the script and thinking 'I've got no idea who James Bond is going to be'.

With Pierce, you kind of knew the inflections, you knew his mannerisms and the style and you could kind of picture the way it would be. I was on set while they were filming Casino Royale, and [my music] was largely informed by the way Daniel moved. He's a very physical, alpha male James Bond, not as eloquent and educated – you know, the idea of knowing which wine would go with what sort of fish – slightly less of that, more that you believe that if he hit you it would really hurt.

And he wasn't James Bond yet: obviously he had the name but he hadn't become the character, so it was really doing away with the comic aspect of it and trying to make it a bit more muscular, as he was, and to make it a little more aggressive, but organic, because the refinements didn't come till later in the film. So you couldn't write the same kind of music for Daniel as you did for Pierce? Well you sort of can in a way because he's still James Bond. This is part of the problem with coming back to the series again and again, it's the same character in very similar situations: there's conflict that he has to resolve, you know there are going to be chases, you know there are going to be fights, you know there's going to be action and even though you have to believe he's in jeopardy, you know that at the end of the film he's not gonna die. So it's a matter of trying to take what people know and expect of the character, moving it on a little bit and introducing other aspects of it, as the films do.

The Bond theme is hinted at throughout Casino Royale but doesn't appear in full until the end credits. Was it hard to resist sticking the Bond theme in? I've always said that a James Bond film without the James Bond theme is just an action movie; there's something you're missing at the heart of the character. With Casino Royale, Sony were quite worried about not having the Bond theme in the score because they were worried it'd be like watching Star Wars without the theme: there's an expectation that you want to hear it. But my argument was that he wasn't James Bond yet, so if you play any of that music when he's doing any of the things he's doing – you know, he makes a lot of mistakes in this film – then he becomes the Bond that we know, but he hasn't done that yet so you can't get ahead of the audience. So there were a few sequences in Casino Royale that tried to create a balance we thought would work: every time he acquires something of the Bond canon that we knew and recognised, I put in a hint of the Bond theme to start sowing the seeds of it as we go through. So when he wins the Aston Martin DB5 in the game of cards you hear it for the first time; when he tries on the tuxedo in the hotel room and we see him adjusting himself in the mirror, that's the second time, and so on until you get the iconic phrase right at the end of the movie.
