Lockup

What is a lockup?

Also called lock-up, or lock off.

A lockup is a position held by a crew member to stop people, traffic, or noise entering the shot during a take.

Urban exteriors are shot on a ring of lockups, and the count is a real line in the day's labor: a busy intersection can need a dozen. Under-staffing lockups produces ruined takes, which is more expensive than the staff would have been.

Example

A busy intersection needs eleven lockups to hold pedestrians and traffic out of frame from every approach. Staffing eight of them means ruined takes, which costs more in crew time than the three extra people would have.

Figures are illustrative, chosen to show the mechanics rather than to quote market rates.

Where you'll see it

Counted at tech scout and staffed from the daily labor budget by the locations department.

Common mistake

Under-staffing lockups to save on daily labor. Ruined takes cost more in crew time than the extra people would have, and the count is knowable at tech scout.
