How low?

I've read that when a film shoot goes too smoothly, chances are good that the movie will be bad. Problems in the narrative or cinematography or direction that aren't addressed during the shoot, simply slip through. The same can't necessarily be said about a rough shoot though. It still may not be any good.

We had a rough set up Saturday for a fairly insignificant close up shot. 3-5 seconds of mostly camera movement, but it took an entire day to set it up -- and this using the same set pieces and lighting. I was the first to lose patience, barking ridiculous statements like "why bother with a storyboard if we have to rework each shot during the shoot anyway!"
After a cool down, Chuck reminded me of all the behind the scenes stories, all the rewrites, all the experiments, all the risks that go into the DVD extras of Criterion films. I'm not normally one to find comfort in sympathetic suffering, but it's nice to think that well planned shoots by seasoned pros see rough days as well.

I find comfort in knowing that a film's made at least 3 times: the screenplay's written, the film's shot, and the footage is edited. It's good to have safety catches. As many as you can.
