"I'll be with The Goat until the fall. Then I've been given three plays to look at and there have been a couple of films have come over the desk. I will probably not do either one of them"

Mercedes Ruehl is likely describing a task she is presently working on, which is likely a play or a film. She is committed to this job until the fall, however after that she has actually been provided three plays to look at and a couple of movies have come over the desk. She is most likely considering these tasks, but she will probably refrain from doing either one of them. This suggests that she is trying to find something particular and is not going to settle for anything less than what she is trying to find. It likewise recommends that she is a dedicated and diligent individual who is willing to put in the effort to discover the ideal task for her.
