Co-production

What is a co-production?

Also called treaty co-production, or official co-production.

A co-production is a picture made jointly by companies in two or more countries, usually structured to qualify for incentives and funding in each.

Official treaty co-productions require a defined split of creative, financial, and technical contribution, all of which the accounting has to evidence line by line. The result is a far heavier reporting burden: parallel cost reports, multiple currencies, and separate qualifying-spend tests.

Example

A treaty co-production splits 60/40 between two countries. Each side has to evidence its share of spend, crew, and creative roles separately, so one shoot produces two cost reports, two qualifying-spend tests, and two currencies to reconcile.

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

Where you'll see it

The financing and legal structure first, then doubled through every accounting deliverable. Audited by both jurisdictions.

Common mistake

Budgeting the accounting effort as if it were one picture. Two jurisdictions means two sets of tests, two audits, and two currencies over the same ledger.

Related questions

What is a treaty co-production?
A picture made under a formal agreement between countries, requiring a defined split of financial, creative, and technical contribution that the accounting has to evidence.
Why does a co-production double the accounting work?
Each country tests its own share of spend, labor, and creative roles separately, so the same costs are reported twice under two different sets of rules.
