I once had a Line Producer say they didn’t need to be on network calls because they weren’t involved with the creative. To that I say, “poppy cock”. The creative drives the production, and as far as you Ms./Mr. Line Producer are concerned ANYTHING that has to do with production concerns you.
Network notes alert you to:
1. New scenes that may have to be shot – whether they are small pick-ups or massive re-shoots
2. Major structural changes to an episode requiring additional edit time
3. Changes to the musical score
All of the above require time and money. Hey you! You are the keeper, watcher and manager of time and money on a production. So yes, network notes apply to you. Changes in the creative apply to you. During production, life in general applies to you.
Good luck, God Speed.
