[Film] editing is a kind of surgery — and have you ever seen a surgeon sitting to perform an operation? Editing is also like cooking — and no one sits down at the stove to cook. But most of all, editing is a kind of dance — the finished film is a kind of crystallized dance — and when have you ever seen a dancer sitting down to dance?
