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
4. Re-writes
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.
