What is the role of the script supervisor in film production?
The script supervisor is the sole guardian of narrative consistency who gathers paperwork and documentation to ensure that a character's drink level, the position of a hat, or the angle of the camera remains identical across shots filmed months apart. This role involves creating a story bible that allows editors to match shots taken on different sets, under different weather conditions, and with different lighting. Before the digital age, this documentation relied on film-based Polaroid cameras to capture the state of sets and actors at the beginning and end of every shooting day.
