Film is shot on the stage, then transferred to video, which is then
digitized onto the Avid computer editing system, which holds every take of
every scene. A scene is shot many times from various angles: wide master
shot, three-shots (3 people), two-shots, singles, raking twos, close
ups, medium shots, extreme closeups and sometimes downshots (as well as
CGI and composite shots).

John Copeland and I then go in and work on the version of the episode
edited by the director to do the producer's cut. We sit down with the
editor, and go scene by scene. The usual construction is as follows: you
get a wide master shot so we know the geography, where we are, and where
everyone is in relation to that. Gradually you go closer, into threes or
twos, then singles or closeups for dramatic emphasis, coming out into the
master from time to time when someone has to move, or to break the sense
of claustrophobia.

When you get in close, you have over-the-shoulder shots, meaning
you're shooting past one character's shoulder to the other. Then you do
the same thing in reverse, so you see both sides of the conversation.
You do these one at a time, for lighting purposes; you light one side of
the room for the scenes looking left-right, then move the camera and the
lighting around for the scenes when you're on the right side looking
left (or, phrased differently, you light for Susan looking at Talia,
then Talia looking at Susan). The actors then do the scene again, with
the camera on the other side.

The actor has to be very careful to always repeat each movement
exactly; if he picks up a teacup on the word "quibble," he has to make
absolutely sure he picks up the cup on exactly that same word, every
time, in every take, in the same way, in the correct hand. If the
actor slips (and this sometimes happens), when you go to show the other
side of the scene, you suddenly find you have a matching problem; in
the shot over Talia's shoulder to Susan, the actor raised a hand; in
the shot over Susan's shoulder to Talia, the actor (generic term that
includes women) *didn't* raise a hand. So when you edit the two, you
have a matching problem. You can sometimes avoid this by just staying
on one side of the shot, but then you can't get the other character's
on-face reaction to what's being said. And in that scene in particular,
we *needed* to see both sides.
