Call Sheet Abbreviations, Decoded: A 1st AD's Glossary
A veteran 1st AD decodes every abbreviation on a film call sheet, from SW and FW to N/C and M.O.S., so your crew reads the same plan and the 5 AM phone calls stop.
Every call sheet reads like a secret code the first time you see one. SW. FW. N/C. M.O.S. A new PA stares at it like a puzzle, and a veteran 1st AD reads it like a weather report. The codes are not there to gatekeep. They are compression. A few letters stand in for paragraphs of payroll and logistics meaning, and when the whole crew speaks the same shorthand, the day starts clean. When they do not, somebody's phone rings at 5 AM. Here is that glossary.
A call sheet is the one document that has to speak to talent, every department, production, payroll, and insurance at once. Full sentences would turn it into a novel nobody reads, so codes keep it scannable and carry exact meaning everyone agrees on. If your 2nd AD invents a new abbreviation on Tuesday, the gaffer misreads it on Wednesday, and that is how a unit ends up at the wrong gate.
Cast engagement codes: SW, H, FW
Next to every actor's name, the AD department records that actor's engagement status for the day. These three codes come from talent contracts and payroll.
- SW means Start Work. The actor's first day, and the day payroll starts counting guaranteed days. Union paperwork keys off it. Mark SW on the wrong day and somebody's paycheck is wrong.
- H means Hold. The actor is not shooting but is held, and paid a hold fee, to stay available. Common on multi-day jobs where flying talent home and back costs more than the hold.
- FW means Finish Work. The actor's last day. After this they are released and travel gets booked. Mark it a day early and you spend the morning rebooking flights.
The AD team tracks these daily because one missed code ripples through contracts.
Hair, makeup, pickup, and the set call
The most misread block on any call sheet is the string of times next to each actor's name. Read left to right, it tells the story of their morning.
- HMU means hair and makeup call, the time the actor sits in the chair. On bigger jobs the AD splits it into H (hair) and M (makeup) for separate stations with staggered starts.
- U or Set means the unit call, the time the actor must be camera ready on set. List hair, makeup, and set call as separate columns, because one lumped time hides the math.
- PU means pickup, the time the driver collects the actor. This is the code most often left blank, and a blank PU line is how an actor ends up calling the 1st AD from a dark parking lot at dawn.
The order is always PU, then HMU, then set call. When I audit a call sheet, I trace one actor's morning end to end. If those three times do not add up, nothing else on the sheet can be trusted.
The shooting schedule codes: INT, EXT, D, N, N/C, O/C, V.O., M.O.S.
The schedule section lists the day's scenes, and its codes come from the screenplay world.
- INT and EXT mean interior and exterior. D and N mean day and night. EXT. PARKING LOT, NIGHT is the full classic, and every department reads it instantly.
- N/C means Not Called. The cast member was considered and confirmed not needed today. N/C says we thought about you, stay home. A name missing entirely says somebody forgot.
- O/C means On Call. The actor stays available and reachable in case the day shifts. Tell talent what O/C means in plain language, or they will treat it as a day off.
- V.O. means voiceover. The actor records dialogue only, sometimes at a different hour or place, so do not block a trailer and chair for them at unit base.
- M.O.S. means shot without recorded sound. Set legend says it comes from a director's accented mit ohne stimme. Either way, the meaning is settled: no dialogue is recorded, and sound plans accordingly.
Add pgs for page count, and the AD, the DP, and the producer all read the same plan.
Call times: general call, pre-calls, and the estimated wrap
The general call, also called the crew call, is the headline time on page one. Bold, big, unmissable. Under it sit the pre-calls, earlier department times for camera, grip and electric, or art. Label pre-calls as pre-calls. If you do not, the art department's 5 AM rigging call reads like the crew call, and you will have forty people standing around in the dark on the clock.
The estimated wrap is the honest best guess at the end of the day. Publish one. Crews plan childcare, second jobs, and sleep around it, and an AD who will not estimate one loses trust fast. If the day runs long, update it.
Locations and logistics: LOC, UB, CM, 2nd U
- LOC is the location, with the full address, nearest entrance, and gate codes. Studio lot is not an address.
- UB is unit base, where trailers, catering, and parking live when they are separate from where the camera rolls. On location-heavy days they can be miles apart, and the sheet has to say so.
- CM is company move. The whole production relocates mid-day. It needs its own time and clear notes, or it eats your afternoon one confused driver at a time.
- 2nd U is second unit, shooting separately on their own call sheet. If their codes appear on yours, something got merged that should not have been.
Keep your codes consistent, or spell them out
The best habit I can give you: put a small legend on every call sheet, especially when the crew skews young, indie, or photo-world crossover. A five-line key at the bottom of page one costs nothing and saves the 5 AM texts. Second habit: never invent a new abbreviation mid-show. If your 2nd AD builds Tuesday's sheet, it must speak the same language as Monday's. Third: when in doubt, spell it out. The abbreviation serves the reader, not the writer, and a spelled-out word never gets misread.
Learn the codes once and every call sheet you ever read or write gets faster. The morning phone calls get rarer. And if you are tired of hand-typing all of this into a spreadsheet the night before, Easy Call Sheets builds these codes, the cast blocks, and the schedule into clean templates.
