The way the Writers Guild divvies up writing credits has always been a bit of a mystery, especially when there are controversies around who wrote what. When Oscar nominations get thrown into the mix, it gets even more interesting. Back in December, I interviewed Alfonso Cuarón, director of Children of Men, and he had some interesting things to say about his take on the writing creds for the film (the WGA credited Cuaron and his writing partner Timothy Sexton, along with three other writers -- David Arata, Mark Fergus and Hawk Ostby, who had worked on earlier versions of scripts for the film).

When I interviewed Cuarón, the fiery director had this to say about the script that he used in filming Children of Men:

" ... So I asked my writing partner, Tim Sexton, to read the book, and I said, okay, I don't want to read the book because I don't want to sidetrack myself or second-guess myself. I had a very clear vision of the movie I wanted to do. So I said to him, you read the book, and based on this movie I'm telling you, there are elements of the book which you will write into the movie. That's what happened."
