How do I find out how to ask Ms Pfeiffer if she would consider playing the part of a clairvoyant?

She is my first pick fo the part of Anna/ 퀸 Malika in a movie that does not have a screen writer yet. The first edition of the book I just got published. It would make a great movie.I have approached every aspect of the story 글쓰기 unconventionally.Why not go about asking this backwards also? Any tips on getting her answer to how she would feel about playing a part in new movie that needs to find someone to put it together first? The part is about a clairvoyant woman who awakens to the fact that she doesn't belong on a strange planet because she is really an angel.
