Hell is a half-filled auditorium.
— Robert Frost

Every writer is a frustrated actor who recites his lines in the hidden auditorium of his skull.
Rod Serling auditorium quote

I suppose that Paderewski can play superbly, if not quite at his best, while his thoughts wander to the other end of the world, or possibly busy themselves with a computation of the receipts as he gazes out across the auditorium. I know a great actor, a master technician, can let his thoughts play truant from the scene...

I've always been fascinated by the difference between the jokes you can tell your friends but you can't tell to an audience. There's a fine line you have to tread because you don't know who is out there in the auditorium. A lot of people are too easily offended.
— Billy Connolly

Acting must be scaled down for the screen. A drawing room is a lot smaller than a theatre auditorium.
