In most forms of storytelling, character is everything. Even narratives we'd describe as plot-driven only work - are memorable, compelling, etc - when we emotionally engage with the characters. Screenwriters are more sensitive to this reality because they are largely collaborative storytellers working in an industry which has a commercial imperative - everything has to work. That doesn't limit us in the stories we tell, as Anthony Mullins, Australian screenwriter and novelist, points out in his new book, Beyond the Hero's Journey - A Screenwriting Guide For When You Have A Different Story To Tell
There are many books that guide storytellers in this era, for screen and off, including those who reference the standard 'hero's journey' and 'three-act' structure. Including those approaches, Mullins' book is particularly useful, not least because I'd recommend it for writers in any genre or format. It's not a how-to, nor is it painfully academic or require wall-covering plot analysis for your WIP.
Screenwriters focus on character and their arcs. Mullins points to how that process plays out in a diverse sampling of feature films, and does so simply, succinctly and engagingly. I recommend it.
