Psychiatry for Actors: Building Characters Using Psychiatric Principles is a textbook for helping actors, directors, and playwrights in creating characters in plays and films. There are no characters in plays and films, who are not impacted by normal and/or abnormal psychiatric and psychological phenomena. It is important to be faithful to the true presentations of behaviors since audience members know from their personal, family, friends, and community experiences of the true presentations of behaviors. It is based upon Donald Fidler's 30 years of experience of teaching medical students, teaching psychiatry residents, teaching acting students, coaching actors, and writing and directing plays and films.
