With all due respect to Jonathon Larson, his version of the story is where the plot was changed. WOW. You are naive and delusional. Yes, he altered the plot of LA BOHEME, at a point when the opera was in the public domain and could LEGALLY be altered.
Your director licensed RENT, a recent show not yet in the public domain, from MTI (which is not the copyright holder, by the way, but a licensing agency which represents the copyright holders), signed a CONTRACT agreeing not to change anything, and then killed off a major character.
A good director researches her show. That does not necessarily mean studying other productions, but it should include studying the show and the intent. In the RENT book, which describes in detail the creative process and is the first place I'd look if I had to research the show's intention, the director speaks about the choice to have Mimi live at the end. He says (I don't have the book in front of me, so I'm going from memory and my quote might be slightly off from the exact words), "I pushed Jonathan about the ending, but that was one issue he refused to budge on. He simply said, 'My show is about life, not death.'"
So no, he would not have changed his mind if he had lived and continued rewriting. Mimi was intended to live.
If you disagree, write your own damn adaptation of LA BOHEME and kill her. It's public domain, you're allowed to do that.
What you are NOT allowed to do is change the text of a licensed property. Major change or not, it doesn't matter, but major changes (such as, I don't know, KILLING A LEAD CHARACTER) are more likely to get noticed and stopped, as yours was.
This is not a bunch of guys in an office whining about their money, or directors who are just bitter they did not think of it first. This is a LEGAL issue. Your director BROKE the LAW, and it is absolutely mind-boggling to me that she refuses to acknowledge that.
You are students. You are young. You don't know any better. I put the blame squarely on the director, who SHOULD know better, as well as the complete failure of education. She had an opportunity to teach the students about academic integrity, respect, and copyright law. If she wanted to change the ending, she should have followed the proper channels and approached Larson's estate, which would have set a great example for her students.
Instead she set the example that you can do whatever the hell you want to someone else's product, and if you get caught, just cry and stomp your feet and cry "artist." Great teacher.
