Callsheets are weird, aren’t they?
They’re legal-size sheets of paper, covered from top to bottom, on both sides, with ten-point font. It’s just packed with information.
For most people the crew call on the front, and their department’s call on the back, is all they’ll ever look at.
Hair and make-up need to know when each actor is coming in. The director and actors of course want to see what they’re filming the next day. If we’re shooting outside, the weather report affects the grips and maybe sound.
So you see, while every item on that sheet is needed by someone, no one needs all of it. It’s simultaneously wasteful and very efficient.
