The number of scenes varies depending on the amount of action
required. On balance, the average TV script has about 60-75 scenes or
shots in it. From time to time, in B5, we've gone as high as 130 shots
in episodes like "Twilight" or "Fall." I think we just blew out our
record here with "Severed Dreams," which has close to 140.
Number of scenes shot on any day depends on how long the scene; you
can do 4 really long shots or 8 fairly short scenes. The amount of
rehearsal varies depending on the scene, how many extras or what kind of
action/stunts are required. The more action, the more you rehearse, to
ensure nobody gets hurt.
