Do authors have a say in who portrays the characters in the movie version of their books?

Answer 1

Whether an author has input on the casting of a film adaptation of their work depends greatly on their contract. Sometimes they will nearly have the final say, and sometimes they are not even present for auditions.

Answer 2

Authors typically do not have direct control over casting decisions for movie adaptations of their books. Casting decisions are usually made by producers, directors, and casting directors in collaboration with studios and financiers. However, some authors may have input or be consulted during the casting process, depending on their contract or level of involvement in the film production.
