One of the most highly anticipated Frontline documentaries of the year premieres this week on PBS. "The Choice" takes a close look at Hillary Clinton and Donald Trump in an unusual way. Rather than interview Trump or Clinton directly, filmmakers interview the people in their lives: childhood friends and former colleagues, for example. The idea is, if we can better understand where they came from and what’s shaped them, we will gain insight into what kind of President each would be. Kelly Brownell talks to one of the film's producers, Phil Bennett.
