There’s a certain safety to making a film culled from the ether of imagined reality. Your idiosyncratic characters are sewn together from the mist of imagination so there’s less risk of real people becoming insulted, angry, hurt, litigious or even homicidal as a result of your fictional film. For some strange reason, I decided to stray from those sheltered waters recently by writing a new narrative film based on the life of my grandfather, David Karr.
