The rights and acquisition department should be able to tell you whether the film rights to the work are available, unavailable, or in the public domain.

If the publisher does not control the rights, check with the author’s agent.

Buying a film’s rights outright allows you to completely control the work’s film rights up front, except for any agreements you may make with the author’s agent or whoever holds the rights before you purchase them.

The agreement may include rights to adapt the literary work into a major motion picture in addition to other routes, such as home videos, sequel or remake rights, advertising and promotional rights, or the right to change any part of the original work when adapting it into a movie.
