Had to make an awkward decision about the shoot, which starts the 25th. We have a really good actor in our cast. Unfortunately he's based in Toronto, and because of his job, he would be literally flying in on the day of the shoot, about two hours before we need him.
I hate to put the entire show in the hands of air traffic control. We had to decide to recast. Shooting a short is high risk enough without having to gamble whether you'll have to call off your day's shooting because someone's plane got held up.
Shooting is in many ways the opposite of writing. In writing (or editing), you can try out anything you like. If it doesn't work, you have the prior draft to go back to. Unless you have a really good relationship with your money, you get to shoot your picture once. Whatever you got, that's your movie.
If you come up with a crazy but promising idea how to rewrite your script, try it, even if only in your head and only for an afternoon. It's one of the joys of being a writer.
