“Your character’s backstory should feel to you that it doesn’t ‘end’ where the story proper begins. It needs to still be there, under the surface. And if it’s strong enough it will help immeasurably in creating a powerful (story).”
Pauline Kiernan is a screenwriter, award-winning playwright, and Shakespeare scholar.
“Pauline is interested in exploring themes of identity and power through strong female characters with sharp wit and humour, and inspirational characters who struggle in their world against inner conflicts. If there is one defining characteristic of her characters it is an indomitable spirit.” http://www.pauline-kiernan.com/
