Getting ready to shoot

I'm at the edge of the great endeavor! I have the script and cast and location and tomorrow I shoot FAt Men Don't Run. It's been a pain to get everyone on the same page and in the same place to shoot as everyone has wildly conflicting schedules ("I can't do saturdays" when no one else can do sunday). I have had other issues with cast, one of the actresses broke her collarbone, then the replacement realized that he had a conflict in scheduling, forcing me to step in. I hope it works out. The Plot moves on.
