What does a script supervisor for film do?

A Script Supervisor, also known as a continuity supervisor, is responsible for ensuring that the film's script is followed accurately during shooting and that all scenes maintain visual and narrative continuity. They keep detailed notes on every shot, track what has been filmed versus what remains, and ensure that everything matches from one take or scene to the next. This includes monitoring actors' positions, props, wardrobe, and dialogue. Their work is crucial for helping editors assemble the final film without noticeable errors or inconsistencies.
