A playwright, also known as a dramatist, is a person who writes dramatic literature or drama. These works may be written specifically to be performed by actors or they may be closet dramas or literary works written using dramatic forms but not meant for performance.

Screenwriters, scenarists, or script writers, are authors who write the screenplays from which movies and television programs are made. Many of them also work as "script doctors," attempting to change scripts to suit directors or studios; for instance, studio management may have a complaint that the motivations of the characters are unclear or that the dialogue is weak.
