This word is iconic in popular culture as something the director shouts to end the shooting of a scene. It even featured prominently in last year’s Best Picture winner.
But it's the film editors who truly "cut" our films down to what we actually see on screen. Deciding what leave in, what to leave out, how to convey the narrative and how to establish pace are just a few of the editor’s extraordinarily important roles.
The work of many other crafts artists, to say nothing of the actors, is finished when the shoot is done. Others, such as the composer, only begin when the shoot is over. The film editor, on the other hand, is there throughout, working with the director until the film is just right.
