I assume a "short film" is anything under 30 minutes, and I think I can write a script about that long. The key is writing a story that I can shoot in places I have access to, and idea largely inspired by the book. I'll have to find friends willing to act, and not care if they end up sucking. The last movie I made was my senior year of high school, and it couldn't be worse than that one. I still have the 3/4" master somewhere. Anyway, with probably less than $500 I could get the equipment I'd need.
To do a feature-length movie, I'd need a better camera. The golden camera right now it a Panasonic unit that can shoot 24 frames per second progressive scan, and my version of Avid understands that kind of video. It's a $3,000 camera, but it'd be worth it as motivation to shoot. I'm not sure if I'd want to make Third Time, my first feature script, as it's a bit rough, but maybe it would be a start. It'd be hard to shoot the cheerleader scene because I'd need a squad and an actress willing to train for the scene (for free, of course).
I guess with all of this technical writing for my book, I feel a need to be creative, be behind a camera again, and create something. I used to get off shooting and cutting stupid documentary stuff, imagine how it would feel to tell a story...
