Selling Film Rights to Your Book

Updated: September 16, 2022

With so many movies based on books, authors often dream about the possibility of selling the film rights to their work.  Though the process can be complicated, and, for various reasons, deals may not come to fruition, an experienced entertainment law attorney can help guide an author through the process and assist in negotiating agreements.


When an author signs a book contract, they may assign various rights to a publisher, including the right to publish and distribute the work in specified markets.  Some rights may or may not be assigned.  Among these are the right to adapt the work for film and television.  The best practice when selling film rights is to retain these rights to maintain control over adaptations, as well as negotiate better terms for compensation than might be otherwise set forth in the publishing agreement.  In any event, no one can develop a film based on a book without seeking permission from the rights owner.


Typically, when a producer wants the film rights to a book, the first step for either side is to seek an option agreement.  In the agreement, the book author (or rights owner) gives the other party the exclusive option to develop the work and determine if there is interest in adapting it as a film before committing to buying the film rights.

An option agreement is not the same thing as a purchase agreement.  An option holder has the option for only a specified time.  The rights owner receives compensation in exchange for reserving the film rights exclusively for the option holder and not offering the rights to anyone else during this period.  The key terms that are generally negotiated in an option agreement are the price and the length of the term, including any renewal terms.

Typically, the price for the option depends on the popularity of the author and the book.  Every time the option renews, there should be an additional payment.  Other than getting paid more, renewal terms are important because film projects take time to develop and to obtain financing.  However, the total length of the terms should be limited so that the option is not tied up indefinitely.

When the option agreement has reached its expiration date, two things may happen.  Either the rights revert to the author in accordance with the option agreement and the parties go their separate ways, or the parties agree to move forward with a purchase agreement.

In a purchase agreement, the parties negotiate the price, including how profits will be shared.  Other points to consider and negotiate are the scope of rights, such as merchandising rights or rights to create other adaptations (e.g., remakes, sequels, television, etc.), and creative control over screenplays.


In scenarios where the author is also the film’s screenwriter, they may need to determine whether it is necessary to become a member of the Writers Guild of America (WGA), a labor union composed of writers of television shows, movies, news programs, documentaries, animation, videogames, and new media content.  If the production company is a signatory of WGA, then the screenwriter must become a WGA member.  On the other hand, if the author is not going to be the screenwriter, then WGA membership is not required.  Either way, if the production company is a WGA signatory, the credit to the book author in the film is usually governed by WGA rules.

To find out if the production company is a signatory company of WGA, the production company can be searched on WGA’s website.  Note that the WGA has East and West divisions with some rules that may vary. 


Separated rights are a bundle of rights for writers of original materials that are provided under the WGA Theatrical and Television Basic Agreement, better known as the WGA Minimum Basic Agreement (“MBA”).  These rights apply to screenwriters, and if the author is also the screenwriter, there is no need to separate rights.

Typically, a screenwriter is employed as a work-for-hire to write the screenplay, and the copyright for the screenplay is owned by their employer, such as the production company.  However, WGA provides certain copyrights to be separated out and conveyed to the screenwriter.  These separated rights allow the screenwriter to do things like publish the script, publish books based on the script or produce a stage version.  This gives the screenwriter the opportunity for additional compensation if a script is later adapted for the stage, published or otherwise exploited.

These various bundles of rights can potentially be very lucrative for book authors and screenwriters.  Good legal counsel is essential since those in the film industry are likely to have much more experience and leverage in negotiations.  If you are interested in protecting your rights as a book author and/or screenwriter, consult an experienced entertainment lawyer for guidance.
