A few years ago at the London Screenwriter Festival, Jeff Norton did a session on how he pitched his TV Series idea and episodes using powerpoint. In this, concept, characters, plot, theme and story were all portrayed visually using a range of pictures harvested from the Internet (though Pixabay and others platforms now offer an alternative way to avoid infringing copyright).
While I don’t have Jeff Norton’s powerpoint on How to build a TV series idea – actually, I don’t think he offered it – I do have his notes on the session which he worked through in regard to his TV Bible for one of his YA (young adult) actions books. Find Jeff’s notes here.
All the best!
