Back to writing scripts. There are people who write and re-write scripts their whole lives, get paid bucketfuls of wonga (money), and may never have had one of their scripts turned into a movie. This is strange but true. These people are usually rich when they are middle aged, and pissed off. They only live in Hollywood; other countries in the world don't appear to support this species. You could be one of these people if you like to read scripts, then go to meetings and say in a knowledgeable and forceful manner why it doesn't work and then suggest better ideas which you, naturally, would write after your Agent has asked for a suitable 6 figure sum. I guess the people who do this job started by writing original scripts, or adapting books and then got employed by Studios. Most of them have degrees in English Literature.
