Frequently Asked Questions

Background casting companies source the background performers needed to bring a scene to life. Extras are supplied to production to create the authentic atmosphere directors envision.

How it works

• Production hires extras and uses their looks and presence to populate scenes.
• On shoot days, background performers are onboarded as production employees and issued digital vouchers — these act as time cards and record rate details.
• Performers also complete required employment forms (I-9, W‑4 or applicable provincial forms).

Payroll & accounting Production accounting uses digital vouchers to process and track background performer payments, replacing the older paper-based system for faster, more accurate payroll.

Productions engage third-party background payroll companies to issue paychecks and handle payroll administration for extras. These payroll providers act as the employer of record in the U.S., managing federal, state, and local tax withholdings and providing workers’ compensation coverage. In Canada, payroll companies handle paycheck issuance and payroll processing, though they are not the legal employer of record.

GreenSlate is a payroll company that processes union and non-union payroll, including digital startwork and timecards.
