Scriptwriters prepare stories and instructions for films, television, plays and commercials. Their role is essential to the production process. Script editors check that scripts meet standards, provide feedback, and manage the relationship between writers and the production team. A scriptwriter's work begins when a director chooses a concept and the scriptwriter creates writing to accompany the director's plan. Writers often find work through directors they know or by pitching ideas to production clients. Types of scriptwriting include radio drama, factual programming, and fiction for film and television. Legal considerations for scriptwriters include copyright, plagiarism, contracts, and agreements regarding the purchase and optioning of scripts.
