"[T]he biggest directors I worked with, that is [Tarkovsky] and Bergman, and of the younger generation Lukas Moodysson, they have one thing in common that they [don't] make the movie on the set but in editing room. They suddenly become not a doer as they were on the set, they are as spectator, they are the audience which it is really defining a good director; the one that can move from having having intentions to having judgment of the audience." (Michał Leszczyłowski)
Andrei Tarkovsky's final film was THE SACRIFICE (1986). During post production he found out he had terminal cancer. Michał Leszczyłowski, his editor on that film, tells the story of how he got the role of cutting the film and then, when Tarkovsky could not finished the edit, took over the editing of the film.
