How can I rock this monologue?

Hay! I would suggest renting the movie and seeing how she does the monologue. (but watch the whole movie so you get the whole context) Also maybe look it up on You Tube or something to see how others have done it. Dont take and do it the same way but put yourself in her shoes and think about how you would feel and then it should come naturally. That is what I have done with many of my Monologues and they turn out awsome. Good Luck!
