It's written by Eric Bagosian, and was originally a Play staged for the theater in New York at The Lincoln Center.
Different directors work in different ways.
A week ago, the whole cast and Rick and Eric got together to read the script 4 times in Los Angeles. There's really nothing more exciting than hearing a piece of Work read over and over and over and over again. When I slept at night in the Hotel, the Whole script filled my being, and rang in my ears like a silver Bell bought at Tiffany's. It Echoed through me, is what I mean. I was already hearing its essense, its meaning, its story, and its plot.
