Dear Ms. Rosenberg
First let me say that I thought you did an impeccable job at screenwriting Twilight from Stephenie Meyer's novel. From what I can see you did a great job on New Moon as well. I can only assume that Eclipse will be no different. You have proven yourself a competent and talented screenwriter. Hell you write episodes of Dexter for goodness sake! Your ability is not in question.
I am here to discuss Breaking Dawn. This will be the ultimate test of your career. If you can manage to pull a workable movie out of that piece of literature you should (hands down) win the Academy Award in screenwriting. Everyone seems to be wondering who will be chosen to direct Breaking Dawn because they believe that is (ultimately) the person who will sink or swim in making a film work on the last book. I beg to differ. This all lies with you and that is quite a big burden to bear. The world is on your shoulders. The movie will make a ton of money so Summit can't be THAT concerned with the script. But I know you aren't a writer to please all the people who will watch anything with Robert Pattinson in it. You actually care about putting out quality work.
So here are my questions. How are you honestly going to manage to write the birth scene and still maintain a PG-13 rating? How are you going to write for Renesmee and her not look like a freak of nature? Regarding Renesmee, the hardest challenge will be for the casting directors/CGI geniuses. They have a daunting and hard and impossible job. The honeymoon scene is what everyone will be flocking to the cinema to see (the rabid fans I mean) and I am sure Mrs. Prude Meyer will be ALL OVER the writing and filming of that. Look I know she didn't write the books for a mature audience and is trying to keep it morally sound. But this is the last movie and we have to have more than just a fade to black. But I know it won't happen because SM wouldn't even let the first kiss scene stay the way Catherine had it (ie Steamy). I find it rather hypocritical that SM has an issue with a tasteful sex scene however has ZERO problem with blood and gore which Breaking Dawn the novel is filled to the brim with. You want to see Edward and Bella consummate their relationship....sorry you aren't gonna get it. But if you are excited to see Edward rip Bella's belly open with his sharp vampire teeth, well you are in luck.
And don't even get me started on how you are going to work out the awful anti-climatic ending. This is going to the be the last film in the series and as a talented screenwriter you know you can't end it that way. Sure if this were an Indie film you could get away with it. But, it isn't.
So in conclusion, I will keep you in my thoughts and prayers while dealing with this huge predicament and the test of your career. You will deserve a Pulitzer if you can pull this off.
(Please note: I have no clue if she has even been signed as the screenwriter for the fourth film).
