If there's an idea I think is really good and I feel like I can write it, then I'll do it.
Being known as a writer did change the relationships I had with directors. The rap on actors is that they always want to inflate their parts. But when directors know you write screenplays and have a different view of things, you really get invited into the huddle in a much fuller way. And those collaborations end in friendships.
If you are writing a story and trying to draw an audience to come and hear you tell it, it's got to in some way relate to them. Who wants to come and hear about your specific problems? It's not therapy - it's supposed to be a communal piece of entertainment.
I've gotten much better at multi-tasking. It's hard, though. But, writing a script is not totally focused. You're taking little breaks, all the time. If a kid runs in, you give 'em a horsey ride. It's a pretty fluid process.
The whole thrust of theatre is different, just because the writing is so much more respected in a play. Whereas in movies - and having been the writer, I can say from experience - the writer is lower down on the food chain.
