I do not know if this is a standard Playwrights Horizons policy or stanard for most non-Broadway houses or not, but I think it it one that ALL theatres should adapt to.
I got an e-mail from PW saying that there will be NO latecomer seating to DEAD MAN'S CELLPHONE until the second act.
Kudos to them! I've unintentionally been late to only one show in my life due to a subway car I was on being stuck for 20 minutes. If I have theatre tickets, I sometimes arrive there 30 minutes prior to the show!
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
