It's not a natural translation, transition, to take something from stage to screen. Onstage your action is communicated through the spoken word primarily, and on screen it's communicated through pictures. So it's always been kind of unnatural to take something that lives on the stage and turn it into moving pictures.
When I write a play, and we read it for the first time, the great fear is that everybody is going to say, 'You're a bum and you can't write. This stinks.' and throw the script in the garbage. The great hope is that they're all going to lift me up on their shoulders and carry me to the streets, singing, 'He's a genius, he's a genius!'
Some people do stage and film. Some people are film actors, and some people are stage actors. I'm quite sure that any of the actors who did the original production of 'August' could have done the film of 'August.' I don't think any of them were particularly surprised when they didn't wind up doing the film.
