For writers that rehearsal period is death. It is the most destructive thing of all to a script.

I have come to the conclusion that one useless man is called a disgrace, that two are called a law firm, and that three or more become a congress.

You listen to the audience. The audience is wrong individually and always right collectively. If they don't laugh, it isn't funny. If they cough, it isn't interesting. If they walk out, you are in trouble.

At early previews, the theater gossips are there, wishing you ill every night. They don't grant you any slack. Agents are in from Hollywood. Your friends are there. People who are going to spread the word-of-mouth. If something doesn't work, everyone will know.

The rehearsal period is so far away from the time when the scene will actually be shot that very little is remembered.

For writers that rehearsal period is death. It is the most destructive thing of all to a script.

Musicals are written and then rewritten. Those things used to happen on the road. Now they are done in New York during preview performances.
