Not formally. I went to a normal comprehensive school, did my A-levels at the local FE college and then onto a Film and Theatre Studies degree in London. The degree was purely academic with lots of critical theory and politics. It broadened my viewing habits and helped me understand the classics. Ironically, I procrastinated from writing my dissertation by writing my first screenplay. Now I procrastinate from writing screenplays.
Since then, I’ve attended a few workshops and lectures but I’ve never paid oodles of money to be told that a script should have a beginning, middle and an end. In my opinion, writers are born not trained. My advice would be to join an organisation like NWN that encourages you to write and interact with other writers. The only way to get better at writing is to keep writing.
