1. Copyright in Film Scripts

Under most copyright regimes:

A film script is considered a literary work.

Protection is granted to the author, i.e., the human who creates the work.

Requirements for copyright:

Originality – the work must reflect human creativity.

Fixation – the script must be written, typed, or recorded.

Authorship – the creator must be human.

When AI assists in scriptwriting, the central questions are:

Who owns the copyright: AI developer, AI user, or co-creators?

Does the human input satisfy the originality requirement?

Is AI simply a tool, or an independent creator?

2. Key Case Laws on AI or Automated Work Authorship

Below are detailed discussions of more than five important cases that influence AI-assisted scriptwriting copyright.

1. Naruto v. Slater

Facts

A monkey named Naruto took a selfie using a photographer's camera. The monkey was not human, yet the photo became famous.

Issue

Can a non-human (animal or AI) be recognized as the author of a creative work?

Judgment

Only humans can hold copyright.

Non-human entities, including animals or AI, cannot be legal authors.

Principle

AI systems themselves cannot own copyright.

In AI-assisted scriptwriting, any protection will belong to a human who contributes creatively.

2. Thaler v. Perlmutter

Facts

Stephen Thaler submitted an AI-generated work entirely created by his “Creativity Machine” and claimed copyright for the AI as the author.

Issue

Can AI systems be legally recognized as authors?

Judgment

Court rejected AI authorship.

Copyright law requires human authorship.

Autonomous AI creations are not copyrightable.

Implications for Scriptwriting

Fully AI-generated film scripts are not automatically protected.

Only scripts where humans provide creative input are copyrightable.

3. Burrow-Giles Lithographic Co. v. Sarony

Facts

Napoleon Sarony took a photograph of Oscar Wilde. A company reproduced it without permission.

Issue

Does a work created with a mechanical device qualify for copyright?

Judgment

Court held the photograph was copyrightable because Sarony exercised creative judgment (pose, lighting, expression).

Principle

If AI is a tool used by a human, and the human provides creative control, the resulting work can be copyrighted.

Application

In AI-assisted scriptwriting, the human screenwriter who directs AI prompts, edits scenes, and designs narrative arcs is likely considered the author.

4. Feist Publications, Inc. v. Rural Telephone Service Co.

Facts

Feist copied a phone directory containing factual listings.

Issue

Are factual compilations copyrightable?

Judgment

Facts alone are not copyrightable.

Only original creative expression qualifies.

Application

AI-assisted scripts that only compile existing clichés, stock dialogue, or pre-existing plots may not be copyrightable.

Originality must come from the human contribution.

5. Nova Productions Ltd v Mazooma Games Ltd

Facts

Players generated images in video games using software.

Issue

Who owns copyright in images created with software?

Judgment

The software developer was the author because the players did not exercise sufficient creativity.

Principle

When a program generates output, the human input determines authorship.

If AI-assisted scriptwriting is guided by detailed creative prompts, the human prompt engineer may hold copyright.

6. Eastern Book Company v D.B. Modak

Facts

Dispute over copyright in edited judicial headnotes and legal commentary.

Issue

Does editorial effort create copyright?

Judgment

Court held copyright exists if work demonstrates skill, judgment, and labor.

Application

For AI-assisted scripts, human editors who refine AI drafts, add dialogues, and craft story arcs may own copyright in the edited manuscript.

7. Acohs Pty Ltd v Ucorp Pty Ltd

Facts

Safety data sheets generated automatically by software.

Judgment

Purely machine-generated documents lacked copyright protection.

Principle

Human creativity is the legal threshold.

Automated AI scripts without human intervention may be ineligible for copyright.

3. Copyright Ownership in AI-Assisted Film Scripts

Scenario 1 – AI as a Tool

Human screenwriter uses AI for:

Generating dialogue ideas

Structuring plot points

Editing scenes

Copyright likely belongs to the human writer.

Scenario 2 – Fully Autonomous AI Script

AI writes the entire screenplay without human input.

Court precedents (Thaler, Acohs) indicate no copyright protection.

Scenario 3 – Collaborative Ownership

Human and AI jointly produce script.

Courts generally favor the human who exercises creative control.

Ownership may rest with:

Human editor

Human director or prompt designer

AI output remains public domain

4. International Approaches

U.S.: Only human authors; AI-generated scripts need human creative input.

U.K.: Programmer may be considered author if software generates work automatically.

India: Skill, judgment, and labor of humans is key; originality must be human-driven.

5. Additional Considerations

Film industry contracts: Often specify ownership of AI-assisted work.

Moral rights: Authors have the right to attribution even if AI contributes significantly.

Derivative works: AI scripts based on public-domain works can have copyright if human adds originality.

6. Conclusion

AI cannot be an author.

Human creativity is essential for copyright in AI-assisted scripts.

Prompting, editing, and shaping the narrative confer copyright to humans.

Fully autonomous AI scripts remain unprotected under current law.

Case law consistently emphasizes human intellectual input and originality as thresholds for protection.
