Production Manager (PM) / Unit Production Manager (UPM)

This person is responsible for managing the budget and the hired crew. They often have a say in who is hired and what equipment is used. They work closely with the Producer and are typically jumping between being on-set or in the office, making sure that everything runs smoothly during filming. A way to tell who is who, is often the Line Producer is on-set while the Production Manager or Unit Production Manager is at the computer.
