To find creative ways of avoiding too much lip-synching but without resorting to a disembodied narrator...through close-ups, cutaways...keeping the story visual and not letting the images become secondary to the words. I find this means the script changes as I go, as interesting visuals suggest themselves. Forgive me (colleagues) but I seldom stick to a storyboard and seldom even draw one. Its mostly back-of-the-beer-mat/ organic flow - or as we professionals call it Zen Animation!

Damn. Now I've realised that, I'm going to have to start being more creative with the shape/ layout/ size of the thumbnails.
Maybe with speech bubbles...
