Do You Have Cover Sets?

I remember going on a scout for a film that never happened actually, in a very remote part of Africa. And the scene probably involved 500 extras or something and then actors. It was fantastic. Another consideration that you should have, I wish all films did, is you've got to think about cover sets. So if you run into the wrong weather on your exteriors, you can pop into this particular scene and you can carry that scene. That's again, actor ability and actual location. Are you going to another city? How you work that out, but yeah.
