One of the most wonderful experiences of attending the San Francisco film festival was watching this fascinating film about film music in one of the theatres at the Dolby Laboratories - experiencing a visual and audio quality rarely seen in a commercial cinema. To be sure, this documentary didn't really warrant a screen that would've done a big budget action movie justice, but the sound quality was much desired. Over 90 minutes, the film-makers give us an amazing insight into the history and current state of composing for film, including a quite dazzling access to composers including the pre-eminent Hans Zimmer.
The impression one gets is that movie composition has changed from writing and conducting a traditional orchestral score to something more akin to a polymath enterprise - creative originality; running a vast team of people; and enough IT knowledge to produce the music. It's the middle part of that that really surprised me - these composers are essentially front-men for a team that includes people who will supplement their creative work, produce scores, and sometimes conduct so that they can be in the mixing booth ensuring the overall mix of the work produced. And now they are supplemented by a new breed of conventional rock star turned composer bringing a new feel to the scores they create.
