Cast, Extras & Stunts
People are the most expensive and most complicated thing to schedule on a film. Getting the human elements right — numbering the cast, counting the extras, flagging the stunts — is where a breakdown earns its keep.
The element categories aren't all equal. The people categories — cast, background, and stunts — are the ones that most shape your schedule and budget, because human beings have call times, meal breaks, union rules, and daily rates. A prop sits in a truck until you need it; an actor has to be booked, scheduled, fed, and paid whether the day runs smoothly or not. That's why the breakdown treats the human elements with special care, and why this chapter zooms in on them.
Cast: number them
The cast category covers speaking roles and principal characters. The key discipline here is that each cast member gets a permanent number — a cast ID used across the whole production. The lead might be #1, the antagonist #2, and so on. Why numbers instead of just names?
- They track an actor across every scene. On the schedule and the day-out-of-days (Chapter XI), "Cast #1" instantly shows every day that actor works.
- They drive availability planning. You can see at a glance which scenes need which actors, so you shoot an actor's scenes together and don't pay them to sit idle.
- They're compact. On a crowded board or schedule, "1, 4, 7" is far cleaner than three full names.
So as you build your breakdown sheets, assign every speaking character a number and use it consistently. The cast list with its numbers becomes one of your most-referenced production documents.
Background & extras: count them
The background (or atmosphere/extras) category is about numbers, not names — you're estimating how many non-speaking people fill each scene. "A busy restaurant" might be 20 background; "a packed stadium" is a different budget line entirely. Precision matters because extras cost money per head per day, and someone has to cast, wardrobe, feed, and manage all of them.
- Estimate a realistic count for each scene ("15 diners," "6 pedestrians") rather than a vague "crowd."
- Watch the difference between silent extras and "silent bits" — a background performer who does a small featured action (reacting, handing something over) may be a higher category and cost than pure atmosphere.
- Flag the big crowd scenes early — they drive location, budget, and logistics far more than the script's word count suggests.
Stunts: flag them, always
The stunts category is small but critical, because it's about safety as much as budget. Anything that could injure a performer — a fight, a fall, a car chase, a fire, even a "simple" trip-and-fall — should be flagged as a stunt so it gets a stunt coordinator, proper planning, and safety measures. New filmmakers routinely under-flag this, treating an action beat as no big deal. On a professional set, if there's any risk, it's a stunt, full stop. The breakdown is where that gets caught, so the right people and precautions are in place long before the camera rolls.
Two hard-won habits. First, I number my cast on day one of the breakdown and never renumber — that number follows the actor through the whole schedule, and it's the backbone of planning their days. Second, I flag anything remotely risky as a stunt, even if the director insists "it's nothing." A performer stepping off a low wall is nothing — until someone lands wrong. The breakdown is where you build in safety by naming the risk early, so it gets a professional and a plan instead of an improvised "we'll just do it." When in doubt, flag it.
People handled, you turn to the things: the objects, costumes, and vehicles that fill out a scene. Props, wardrobe, and special elements — and the fuzzy lines between them — are next.
The Scene Analysis tool reads your script scene by scene and surfaces the elements in each one — cast, props, locations, and more — giving you a head start on a full breakdown instead of marking every page by hand.
