An Artist Playing An Artist?

Or maybe it's more a matter of an unprepared actor playing a self-involved painter who runs off at the mouth... A LOT! We were forced to change scripts, and the size of my role has increased considerably. (I've killed 2 highlighters working on this script.) The show opens the 1st week in March and I feel a little pressure because we've had to start all over from square 1. It's a good group of people, an interesting play, and a tight deadline. That doesn't always make for a relaxing, exploration rehearsal process. It's going to be interesting.
