In 2013, financiers kept passing on a script called Whiplash. So Damien Chazelle shot fifteen pages of it as a short for $23,000. It won the Short Film Jury Prize at Sundance, Bold Films financed the feature at $3.3 million, and the film grossed over $50 million and won three Oscars. The short was not marketing for the film. The short was the argument for the film.
That is not a one-off. It is the most reliable pattern in independent film finance, and it has a paper trail. Here is the ledger.
| Feature | The proof | Feature budget | Worldwide gross |
|---|---|---|---|
| Whiplash (2014) | 18 min short, $23,000 | $3.3M | $50M+ |
| Saw (2004) | One scene from the script | $1.2M | $103M |
| Lights Out (2016) | 3 min short, shot at home | $4.9M | $148M |
| Smile (2022) | 11 min short, SXSW 2020 | $17M | $217M |
| District 9 (2009) | 6 min short | $30M | $210M |
| The Evil Dead (1981) | Within the Woods, $1,600 | ~$375K | $29M |
| Napoleon Dynamite (2004) | Peluca, ~$500 | $400K | $46M |
Read the middle column, not just the last one. In every case the short did the one thing a script cannot: it let the person with the money stop imagining and start watching. Saw was greenlit off a single scene James Wan and Leigh Whannell shot from their own screenplay. Sam Raimi screened Within the Woods to investors specifically to raise The Evil Dead's first money. Sling Blade's short was, in its producers' own telling, shot in the hope it would raise the feature. It raised all of it.
A working sizzle editor put the mechanism in one line: most people are not going to read it. The tape travels with the pitch materials because an executive will watch three minutes on a phone between meetings and will not read a hundred and ten pages before Thursday. A screenwriter whose script had already scored an 8 on the Black List shot a concept trailer anyway, and said it got him more reads than the score, the festival finals, or anything else he did.
Even borrowed footage moves a room. Stranger Things was passed on more than a dozen times before the Duffer brothers walked in with a lookbook and a reel cut from Jaws, E.T., Halloween and Poltergeist under synth music. That reel is a rip reel, not a proof of concept, and it still helped sell one of the biggest shows of the decade. Original footage does more, because it proves you can execute, not just curate. But the lesson is the same either way: the room decides while it is watching.
Documentary has this easy. The standard doc budget template literally contains an account for the fundraising sample. Narrative does not. I have been through the public budget templates, and there is no standard proof-of-concept line in a narrative development budget. The piece gets financed before the budget exists: out of pocket, the way Raimi shot Within the Woods and David Sandberg shot Lights Out in his own apartment, or by a producing partner and a private investor, which is how the Whiplash short got made.
That sounds like bad news. It is actually the argument for keeping the cost small. The proof of concept is the money you spend before anyone has agreed to spend money, so every dollar of it has to be defensible to exactly one person: you.
The industry has priced this object in public. The Proof of Concept Accelerator produces narrative proof-of-concept shorts at $50,000 each. Screen NSW funds them at up to AUD $45,000. The screenwriter I mentioned above reported that a decent proof-of-concept short runs $5,000 to well over $25,000. Those are the published numbers for shooting one from scratch.
Cutting one from material that already exists sits at the bottom of that whole range, because it is an edit, and an edit should be priced like an edit. I charge $5,000 for a first project, fixed. If someone quotes you $50,000, they are quoting you a production. Sometimes a production is exactly what your project needs. Make sure that is a decision you made, not a quote you accepted.
Know the numbers before you take the call. That is all this piece is for.
