Directors and producers often work under stress as they try to meet schedules, stay within budget, and resolve personnel and production problems. Actors, producers, directors, cinematographers, and camera operators face the anxiety of rejection and intermittent employment. Writers and editors must deal with criticism and demands to restructure and rewrite their work many times until the producer and director are finally satisfied. All writers must be able to withstand such criticism and disappointment; freelance writers are under the added pressure of always looking for new jobs. In spite of these difficulties, many people find that the glamour and excitement of filmmaking more than compensate for the frequently demanding and uncertain nature of careers in motion pictures.
