The Greeks used to use the same stories, the same mythology, time after time, different authors. There was no premium placed upon an original story, and indeed, Shakespeare likewise. A lot of people wrote plays about great kings. They didn't expect a brand-new story. It was what that new author made of the old story. It is probably the same now. We disguise it by inventing what seem to be new stories, but they're basically the same story anyway.
Arthur MillerThere is a problem on the so-called commercial stage in New York. The price of a ticket is exorbitant, and there are no longer original productions possible, apparently, on the commercial stage. They are all plays that were taken from either England or smaller theaters, off-Broadway theaters, and so on. The one justification there used to be for the commercial theater was that it originated everything we had, and now it originates nothing. But the powers that be seem perfectly content to have it that way. They don't risk anything anymore, and they simply pick off the cream.
