He is a “professional expert,” a talking head that can glue everything together, a man who’s always got the perfect sound bite for any documentary, whether it’s about Winston Churchill, Woodstock or the color blue. In “Glue Man,” Nick tells the story of how he went from go-to man-on-the-street at his local news station to broadcasting legend at the History Channel. With clips from Nick’s extraordinary body of work and testimonials from esteemed colleagues, the short film finally reveals the secrets of this unsung hero of the documentary business.
