Playing the part of Sam Malone today: Ignatz Gloogdeberg

After a sitcom has been on the air for a number of years – like ten -- it’s understandable that the cast loses a certain amount of interest. They know their characters so well and they know the routine so well that they don't require as much rehearsal as in the early discovery years.

Also, they become big stars by year ten. They suddenly have movie careers. They front worthwhile charities. They start their own production companies and split their attention between the show and their various new projects. They buy homes on the east coast and have to let the painters in.

On CHEERS during the last two seasons the runthroughs were unlike anything I’d ever seen. First let me say that I adore the CHEERS cast – every one of ‘em. They’re great people, terrific actors, and very respectful of the writers and everyone on the crew.

But for those last few seasons they often had other obligations and would miss rehearsal. Like I said, they didn’t need it. The only problem was that we writers did need to see a runthrough to determine what worked and what didn't.

And there were times we would go down to the stage for a runthrough and it would be the first assistant director playing Sam, the script supervisor playing Rebecca, the prop guy playing Woody, the wardrobe girl playing Carla, George Wendt and John Ratzenberger. This is what I assume community productions of PHANTOM OF THE OPERA look like.

We’d go back to the room and have no idea what we had. Someone would say, “I don’t think this Sam joke works” and the rest of us would say, “How do we know? Ignatz Gloogdeberg played him.” It was insane.

The craziest was the time we cut a certain actor’s joke who wasn’t at the runthrough. The actor came in the next day, was annoyed that the line was gone, and chided the stand-in for not selling the joke sufficiently.

In fairness, runthroughs with 80% understudies didn’t happen every week, although it was not unusual to have at least one person out for a rehearsal. That the episodes held together so well is also a testament to how well we writers knew the show and could write for it.

The filming nights would be a little rocky because not everyone knew their lines perfectly. But they would always rise to the occasion and on the air CHEERS appeared as polished as ever.

Although… if I'm being 100% honest --  there were times we writers would be on the stage watching the filming and say, “Hey, Zelda did a better job of that joke.”
