It's not just movies you know. It's also books and stories. Unless you plan on writing YA (Young Adult) books. Good luck on the story circuit. A lot of people think that stories have to have sex and graphic descriptions. I refuse to go there in writing. I lke the tameness of Young Adult literature. There are good morals and good decent characterizations.
I am also writing a screenplay for my last semester of my university life. Now the things in my screenwriting class, some of the scripts are enough to make a sailor blush. Now I am only writing a 25 page script, but my material is good and clean. Their is no sex, and the romance is a cheesy teen comedy story, which is in the style of The Sisterhood of the Traveling Pants and pehaps a bit of Ugly Betty. But it's all clean and nothing dirty. It's possible to write something clean, but I doubt he writers will do it.
I cringe at the word censorship. I want to write whatever comes into my head, but just to let you know my head is mostly clean. One has to wonder what is in the heads of other writers.
