Every continuity error you have ever noticed in a Hollywood film, a coffee cup appearing and disappearing, a wound switching sides, an actor’s tie suddenly unknotted, is a moment a script supervisor was either overruled or overwhelmed. This is one of the most mentally demanding jobs in the industry, and one of the least understood. If you want a career that puts you at the center of every single scene, working directly with the director and editor from day one of prep to the final cut, this role deserves your full attention.
