Breaking Bad is the first series that I watched which had continuity going over multiple seasons.
How do producers and Directors plan series like these which go on for period of multiple years. I mean say, while Breaking Bad was still being shot and Bryan Cranston would have been affected by health issues which would restricted him to shoot for long time. Or say, some actor playing important role meets with an accident (Heath Ledger type of accident).
How do Producers and Directors plan to cope up in case of such huge loss.
