Movies take a long time to film, and that means they are rarely shot in chronological order - but the end result has to look seamless. Script supervisor Alana Marmion-Warr spills the beans on how a film stays consistent, and shares stories of working on Wonka, The Crown and Ready Player One.

This is Out of Frame, where we celebrate and explore the work of below the line roles in film and TV. Out of Frame is produced by Platform Media for CrewHQ at Warner Bros. Studios Leavesden.
