Where/How can I find The Other Boleyn Girl in a Screenplay?

Does that make sense? I have this wonderful idea for a plot I'm working on and was just inspired while at a play. It suddenly came to me, that The Other Boleyn Girl, in a play, would be sure to make my plot more scandalous. I want to look at other plays to maybe get ideas for something that I would be maybe writting later on. Where can I find one?
