All your preproduction planning is done, your cameras are loaded, your cast and crew are in place, the coffee is hot, and the bagels are fresh. What else could you possibly need before you start shooting?

The production phase of filming may seem like the most glamorous, but as any industry pro can attest, it takes plenty of hard work and supreme planning.
