Christopher Boone of NoFilmSchool.com has put together five videos of award-winning screenwriters talking about their writing process.
There’s absolutely no reason you can’t write in ANY genre if you are prepared to put the work in. Genre is craft. Craft can be learnt. So learn the conventions of the genre you want to write. Watch all the movies in that genre, big and small; read all the scripts. Go to events, learn about it. Read articles, blogs, soak it all up.
