How will they make Breaking dawn so that it isn't rated r?

That is the question, isn't it? The problem is doing a film based on a book is two fold: What works on the page may not translate to the screen and if you change anything you risk offending your main base. For "Breaking Dawn", you're right. A straight translation would be R if not NC-17.

It may be tricky, but I think can be managed. For some of the bloodier scenes, they may try to rely on our other senses. Remember, "The Texas Chainsaw Massacre" was not r rated when it came out in the 70's. For a film to be scary (or just effective) they don't have to show everything. They can cut away, use only sounds or shadows, (if they want to include all the scenes from the book) or they may try to rewrite the scenes in question.
