What are some unique things to explore inside certain theatres before the show starts?
For example, at the New Amsterdam, you can stand on the sweet spot by the steps that lead up to the mezzanine and whisper to your friend standing on the stairwell.
At the Gershwin you can visit the Theater Hall of Fame exhibits as well as some set pieces cut from WICKED'S tryout.
At the American Airlines there is a unique lounge on the mezzanine level with a patio that faces 43rd street. There are also plaques and a Tony Award on display.
Not Broadway, but outside Stage 1 at New World Stages there is a wall of fan signatures from the RENT production.
"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."
--Aristotle
