TL;DR. A package is the bundle of commitments that lets somebody else write a check: script, director, cast, a sales agent or distributor, a real budget, and usually some money already in the room. Cast is the piece that moves the number, because a recognizable name is what a foreign distributor will pay a minimum guarantee against, and those guarantees are what a bank lends on. That's why every name has to match the budget tier you're actually in, and why a letter of intent from an actor is not an attachment and most financiers won't count it.

I'm learning how to produce. Not casually off YouTube. I hired a company to teach me, and I'm doing the assignments. In a script, the B story runs underneath the main one. It's quieter, and it's usually where the character actually changes. Mine right now is the business, and I expected to tolerate this part, but I actually like it.

So what is a package, actually?

A package is not a pitch and it isn't a lookbook. It's the set of elements a financier can underwrite: a script, a director who can plausibly finish the film at this budget, name talent, an executive producer who can open doors to money, a sales agent or distributor so investors have a path to recoupment, a deck or business plan, pro-forma financials down to a top sheet and a breakeven analysis, and some of the money already committed. Guerrilla Rep Media puts that last piece around 10 percent, a development round you raise before the production round.

Writers get trained to think of all this as what happens after you're done. Somebody else makes the calls and runs the numbers, and you wait by the phone. That's a bad deal, and it isn't even true anymore. Los Angeles on-location production finished 2025 down 16.1 percent from 2024 by FilmLA's count, and in a market that thin the people who understand both ends are the ones who keep working.

Why does one name change the whole budget?

Because of how indie money gets assembled. A presale is a license where a distributor in one territory pays a minimum guarantee for the rights, usually for 15 to 20 years, typically 10 percent on signature and 90 percent on delivery. A bank will advance roughly 70 to 90 percent of that guarantee's face value depending on the distributor's strength, and those contracts are the backbone of the capital stack.

A distributor in Germany or Japan or Brazil isn't buying your theme. They're buying a face their audience knows in a genre their audience buys. The cast sets the guarantee, the guarantee is what the bank lends against, and the loan closes the budget. That chain runs straight through casting.

What's the difference between an attachment and a letter of intent?

This is where most first packages fall apart. A letter of intent is a non-binding note, often from an actor's manager rather than the actor, saying they're interested if the money comes together. Jeff Steele, writing in TheWrap, was blunt about it and nothing has changed: LOIs are not binding, they're usually out of date, and financiers ignore them. He describes a deal that died when a co-financier called the agency and got the attachment denied.

A real attachment is paper with teeth. Pay-or-play means the actor gets paid whether or not the film shoots, and that's the commitment a bank treats as collateral. It also means you need money before you can make the promise, which is the loop every first-time producer runs into. A letter of intent from a sales agent is different and does carry weight, because it's evidence of access to distribution rather than a claim about somebody's calendar.

Who decides what a cast list is worth?

The sales agent. They produce territory-by-territory estimates of what the film could bring in with a given cast, and those estimates are the document the money actually reads. Lenders don't take them at face value. They apply a haircut of roughly 50 to 70 percent, so a $3 million estimate on unsold territories gets underwritten closer to $1.5 to $2.1 million.

That discount is why the budget tier matters. Standard gap financing, the loan against unsold territories, covers about 10 to 15 percent of a budget. Past 25 percent you're signaling weak presales or inflated estimates, and above 30 percent is close to impossible right now. Gap money is expensive too, 8 to 15 percent annual interest plus a 7 to 15 percent origination fee up front.

The guild agreements make the tiers concrete. Under SAG-AFTRA's low budget agreements for the year starting July 1, 2026, Ultra Low Budget applies at $300,000 or less and pays $256.60 a day. Low Budget covers $700,000 to $2 million at $834 a day. Above $2 million you're into the standard agreement and real quotes. At the low tiers, casting depends almost entirely on an actor wanting the part, because the scale money is not an argument.

Two films I keep coming back to. Whiplash. Damien Chazelle wrote and directed it, financed by Bold Films at $3.3 million, and it exists because an eighteen-minute short cut from fifteen pages of the script won a jury prize at Sundance and brought investors in. Nightcrawler. Dan Gilroy wrote and directed it, $8.5 million, with $2.3 million from the California film tax credit and Jake Gyllenhaal on as producer as well as star. Both grossed around $50 million worldwide, and in both cases somebody built a reason for the actor to say yes before the financing followed.

So a cast list isn't a wish list. It's an argument, and every name is a claim about who the movie is for, what it costs, and whether that person is reachable at your level. Put a twenty million dollar actor on a three million dollar movie and you've told your reader you don't know the business.

Where does AI belong in this, and where doesn't it?

Now the part that gets me in trouble with other writers. This is a good place for AI.

Not the script. The script is mine. But the research around a cast list is enormous and tedious and mostly public record. Who's attached to what, who's worked in this genre, who's at which agency, what the last three comparable films did at what budget. That's hours of work that doesn't need my imagination, it needs my judgment, so I get the list fast and spend my time deciding instead of searching.

Two cautions. Representation and availability go stale fast, so anything that matters gets verified with a call, the way Steele says. And a comp is only useful if the budget, genre and release pattern match, because a tool will happily hand you one that flatters you. That's the line I'm drawing. AI near the business, nowhere near the page.

Before you put a name on your cast list, run this checklist

What budget tier am I in, and does this name work at that tier or only at three times it?

Is this person reachable at my level, through someone I or my producers can genuinely call?

Do I have anything better than a letter of intent, and if not, what would pay-or-play paper take?

Which sales agent would represent this film, and have I seen their estimates on a comparable title?

How much of my budget is still open, and is that gap inside the 10 to 15 percent a lender will consider?

Which three comps am I using, and do they match my budget, genre and release pattern?

Have I verified every attachment claim with the representative, so nothing falls apart on one phone call?

My first assignment taught me that the business end isn't downstream of the writing, it's a parallel draft of the same story told to people who have to risk money on it. If you want your script made and not just admired, learning to write that second draft isn't a betrayal of the first.
