Shooting schedule in practice
It is built by the first assistant director from the script breakdown. Scenes are almost never shot in story order: they are grouped by location, by actor availability, by day or night, and by what is cheapest to move. The schedule is revised many times and each version is dated.
Everything else hangs on it: call sheets, equipment rentals, location permits, catering and the budget.
Where it lives in CrewDesk
CrewDesk shows shoot days on a shared calendar next to deliveries, fittings and scouts, so a clash between two productions is visible weeks ahead. Each event is linked to its project.
