"From novel to movie..."

The cartoons are back! I often see posts on social media from people daydreaming about what they'd do if a producer wanted to by their novel to turn it into a movie. They almost invariably state that they'd only sell it if they had a say in what was done with it. Honestly, if a producer offered me MONEY to turn my novel into a movie, I'd let them do what they wish with it, from changing the gender of all the main characters to setting it in a different time period. 

Maybe that comes out as a bit...greedy? But hey, $ is $. And even if the film is rubbish, then you have the satisfaction of hearing people say that the book is way better.
