FACT OF THE DAY: A film set has many moving pieces all going on at the same time. Crews set up the next scene while the actors prepare. Walkie Talkies are everywhere with constant back and forth communication. Two frequently heard terms while filming are “10-1” and “10-2”. What do they mean? 10-1 means you are going to the bathroom to go #1 while 10-2 means you are going to go #2.
