Who Owns a Film? A Short Map of Rights in an Audio Visual Work

Ask who owns a film and the honest answer is that ownership is a stack, not a single title.

The underlying literary work sits at the base. Above it sit the screenplay, the music and lyrics, the sound recording, the performances and finally the cinematograph film itself. Each layer has its own author under the Copyright Act, and each layer travels to the producer only through a written assignment or a contract of service.

Diligence work is the practice of testing that stack. You are looking for a clean line from every contributor to the producer, then from the producer to the platform. A missing writer's assignment or an unsigned performer release is not a technicality. It is a gap in the chain.

Moral rights complicate the picture further. They stay with the author even after economic rights move on, which is why credit clauses matter more than they look.

The practical lesson from diligence files is simple. Ownership is only as strong as the weakest document in the chain, and the weakest document is usually the earliest one.
