What is a script doctor?

A script doctor is a professional screenwriter who is hired to revise, improve, or fix an existing screenplay. Their work may involve tightening dialogue, enhancing characters, adjusting the plot, or resolving structural issues. Script doctors are often brought in during the later stages of script development, sometimes without official credit, to ensure the script is ready for production. They play a crucial role in refining scripts to meet the creative vision of filmmakers and producers.
