Generally those that license a production from Samuel French or Dramatist's or Bakers or a similar publisher are not allowed to change the text unless there are suggested cuts for high schools included in the book. But with plays that are not copyrighted, such as Shakespear or Oscar Wilde, the director can change the script however they like Other changes to a play may be chage of locale, or time.Shakerspeare for example is often done in modern dress or a different historical time than the Elizabehan period. Some directors think it is within their artistic perogative to alter the play any way they see fit, but in reality changes should be organic, which is to say verifiable in the script. So try to do some research. Get an acting script of a play that is published by one of the companies I mentioned and read the copyright page. Do a web search on How Dirctors Interpret Scripts. IF you use my ideas here, quote me and give me a footnote. I am identified in my profile.
