Carradice: I wonder how did you started working on scripts? What would you suggest to someone interested in doing so?
I used to write little short stories as a kid and I was watching as many films as I could - world cinema, experimental, classics, mainstream, modern, etc. I usually would spend my free time just looking up films I hadn't heard of before and finding ways to watch them (preferably I'd buy them on DVD or blu-ray but unfortunately not every film is available this way).
I studied a BA on filmmaking before starting my MA in Screenwriting although you don't necessarily have to do that really as long as you learn basic screenwriting formatting, structure, characterisation, thematic development - the tools necessary for writing a screenplay. Basic formatting is easy-peasy when you use Final Draft or Celtx (Final Draft is usually the industry standard but it's also quite pricey), the software makes it a lot easier to format your scripts.
If you want some good book recommendations for screenwriting, here's some I'd recommend:
John Yorke's Into The Woods - I know I mentioned it already but it's a fab way to get a good, thorough understanding of structure, writing characters, writing dialogue and building scenes without it becoming overwhelming. The book also includes handy diagrams and tables of different variances on film structure.
Robert McKee's Story/McKee's Dialogue - Story and Dialogue are two different books but are such detailed understandings of how to develop the structure, dialogue and characters in your scripts. McKee is such a good go-to writer for this stuff, he has detailed examples and can be easy to follow, albeit a little overwhelming as Story is quite a dense book.
David Corbett's The Art Of Character - fantastic, accessible read on how to detail your characters. You don't need to apply everything he says to a single character, but it's fascinating and very useful to see what would and wouldn't work for the characters you are writing. His experience is usually in novels but the book gives a great insight into characters for novels, screenplays and TV.
Clive Frayne's The Process Of Screenwriting - A really gentle way to get into different aspects of screenwriting. World-building, writer's voice, visualisation, themes, characterisation, Clive gives a really easy breakdown of all of these. He also goes into some personal reflections about his own experience as a writer which are interesting too. This book definitely makes writing scripts a lot more easier to understand.
I hope these might be useful for you! All the best!
