I know how basically every page is to be 1 minute of screen time, but how do you figure in action scenes with no dialoge? I mean if you have people running thru corridors till they come to a spot to rest. Or a better example would be the big underwater fight scene in Thunderball. Is it up to the director or fight corridoranitor to decide on the lengeth? Because you can have a script that runs say 90 odd minutes, but once you put in all the action wouldn't that stretch it out to a feature?
