That's often lost when we deify directors. Although I would say that actors are often more affected by editors than the director. An actor can give a 90% shitty performance but if the editors picks the right 10% and frames it well, the performance seems amazing.

Some Directors essentially cut the movie themselves from a very comfortable leather couch. Other Directors trust the Editor they employed and only make sporadic trips to the edit bay.
