Rather than using a camcorder to shoot the film, I am thinking of using my digital SLR on a high speed shooting setting to create a more stop-motion feel to it. This will also make it look a bit disjointed and unstable much like the sufferers lifestyle would be. I could possibly draw the movement of picking up the phone and putting it down again as a drawn stop motion animation. Repeat this 5ish second animation over and over. I could have a bit of both styles, film stop motion as well as drawn. Have flashes of the 'bad thoughts' in film, and the phone action drawn. Would it look strange having both? Hopefully not if they're both connected in the style of stop-motion. I will try!
