I was watching the movie "The Princess Diaries" recently and it got me wondering how much control does the author have over the movie adaptation ?
The movie and the books digress on the most pivotal plot-lines like (i read all the books and the side books of this series)
- Boyfriend of the princess is one of the main plot of the books but hes not even a part of the 2nd movie (in the book, the princess actually makes a sarcastic reference to the movie breakup)
- Father of the princess is dead in the movie, but alive in the books
- Movie grandma is good vs book grandma is evil.. etc.
- the part 2 is not even based on the books
So when major changes like this happen in the movie, does the author have a say in it?
