I think there's something to be said about pacing yourself.
A movie contains literally tens of thousands of ideas. They're in the form of every sentence; in the performance of each line; in the design of characters, sets, and backgrounds; in the locations of the camera; in the colors, the lighting, the pacing.
Comic-strip artists generally have very modest ambitions. Day to day, we labor to fit together all these little moving parts - a character or two, a few lines of dialogue, framing, pacing, payoff - but we certainly don't think of them adding up over time to some larger portrait of our times.
The craft of writing is all the stuff that you can learn through school; go to workshops and read books. Learn characterization, plot and dialogue and pacing and word choice and point of view. Then there's also the art of it which is sort of the unknown, the inspiration, the stuff that is noncerebral.
Mick Jagger knows how to run a show. It's all about pacing. It's not a sprint, it's a marathon. His output is amazing, but his movements are subtle. As I get older, I'll have to adhere to these rules.
When you tell a story, there are imperatives of structure, of style, of pacing and all of this, that are there simply because you want to make it a good story. When do you introduce your characters? When do you put them onstage, when do you take them off the stage? How do you weave the different threads of the narrative together?
Warwick Davies is a cracking actor. The opening scene in the last 'Harry Potter' film, where he plays a captured Griphook, is mesmerising. His pacing is sublime, and the menace and regret he builds into the scene is fantastic.
So it's one of those things where we have to - our problem is pacing ourselves and still reaching a large enough number of our audience. Because we don't want to burn the audience. And we don't want to be excluding anybody.
