Yea, sure... theres Wikipedia pages out there with the dictionary meaning of the word... but I'm not interested in that.
What EXACTLY is the directors job? Surely its not just saying "ok, you stand here... and you stand there... all ready? Roll camera.... take 1....ACTION".
It’s a little more than that, but not much.
When the director is working with people who are equally skilled -
or better skilled - at their craft, there isn’t much more to do
than guide them to create what the director wants.
Good actors don’t need much more than “Okay, you stand there and
move to there on this line.”
An excellent DP knows where to place the camera to get the shots
the director wants so the director doesn’t need to say much more
than “I want...” and fill in the blank.
A skilled editor can look at a script and hundreds of set up and
takes and piece together a coherent film.
As long as the director has the vision and is good at motivating
people there isn’t much more to say than, “Stand there, put the
camera there, cut sooner.”
Of course it's kind of like saying that a baseball player's job is just
to catch the ball when it gets close or hit the ball at the right time
and run fast. That's pretty much it, but not all players are equal.
Sidenote: Do you really need a chair with the words "director" all over it?
Yes. Because if the chair says “actor” all over it an actor will sit
in it. If it says “DP” all over it, the DP will sit in it. It’s
nice to have a specific chair that no one else is using when the
director wants to sit down.
