Question - Montage

I've a question.

Some guy is insisting that Michael Kahn had the final word on how the Indy flicks were supposed to look.

I know that Spielberg and Lucas had the final word and is their decision what add and what delete from the final cut.

Is that true? Because the guy claims that the movie editor has the final word on how the movie /any movie/ will look in the final cut...

I guess the editor has a lot of input, but in the end the director is the uber-boss.

Kahn has edited so many of Spielberg's movies, that they must have a very good working relationship.
