Release form in practice
The most common are the talent release, the location release and the materials release for artwork or logos that appear on screen. Broadcasters and distributors ask for them among the deliverables. Wording depends on the country and on how the film will be used, so productions have their forms reviewed by a lawyer.
Where it lives in CrewDesk
Signed releases are uploaded to the project documents in CrewDesk, so they are easy to find when the distributor asks for them a year later.
